1.2 Device Description
The 56F8335 and 56F8135 are members of the 56800E core-based family of controllers. Each combines,
on a single chip, the processing power of a Digital Signal Processor (DSP) and the functionality of a
microcontroller with a flexible set of peripherals to create an extremely cost-effective solution. Because
of their low cost, configuration flexibility, and compact program code, the 56F8335 and 56F8135 are
well-suited for many applications. The devices include many peripherals that are especially useful for
motion control, smart appliances, steppers, encoders, tachometers, limit switches, power supply and
control, automotive control (56F8335 only), engine management, noise suppression, remote utility
metering, industrial control for power, lighting, and automation applications.
The 56800E core is based on a Harvard-style architecture consisting of three execution units operating in
parallel, allowing as many as six operations per instruction cycle. The MCU-style programming model and
optimized instruction set allow straightforward generation of efficient, compact DSP and control code.
The instruction set is also highly efficient for C/C++ Compilers to enable rapid development of optimized
control applications.
The 56F8335 and 56F8135 support program execution from internal memories. Two data operands can be
accessed from the on-chip data RAM per instruction cycle. These devices also provide two external
dedicated interrupt lines and up to 49 General Purpose Input/Output (GPIO) lines, depending on peripheral
configuration.
1.2.1
56F8335 Features
The 56F8335 includes 64KB of Program Flash and 8KB of Data Flash (each programmable through the
JTAG port) with 4KB of Program RAM and 8KB of Data RAM. A total of 8KB of Boot Flash is
incorporated for easy customer inclusion of field-programmable software routines that can be used to
program the main Program and Data Flash memory areas. Both Program and Data Flash memories can be

independently bulk erased or erased in pages. Program Flash page erase size is 1KB. Boot and Data Flash
page erase size is 512 bytes. The Boot Flash memory can also be either bulk or page erased.
A key application-specific feature of the 56F8335 is the inclusion of two Pulse Width Modulator (PWM)
modules. These modules each incorporate three complementary, individually programmable PWM signal
output pairs (each module is also capable of supporting six independent PWM functions, for a total of 12
PWM outputs) to enhance motor control functionality. Complementary operation permits programmable
dead time insertion, distortion correction via current sensing by software, and separate top and bottom
output polarity control. The up-counter value is programmable to support a continuously variable PWM
frequency. Edge-aligned and center-aligned synchronous pulse width control (0% to 100% modulation) is
supported. The device is capable of controlling most motor types: ACIM (AC Induction Motors); both
BDC and BLDC (Brush and Brushless DC motors); SRM and VRM (Switched and Variable Reluctance
Motors); and stepper motors. The PWMs incorporate fault protection and cycle-by-cycle current limiting
with sufficient output drive capability to directly drive standard optoisolators. A "smoke-inhibit",
write-once protection feature for key parameters is also included. A patented PWM waveform distortion
correction circuit is also provided. Each PWM is double-buffered and includes interrupt controls to permit
integral reload rates to be programmable from 1 to 16. The PWM modules provide reference outputs to
synchronize the Analog-to-Digital Converters through two channels of Quad Timer C.
The 56F8335 incorporates two Quadrature Decoders capable of capturing all four transitions on the
two-phase inputs, permitting generation of a number proportional to actual position. Speed computation
capabilities accommodate both fast- and slow-moving shafts. An integrated watchdog timer in the
Quadrature Decoder can be programmed with a time-out value to alert when no shaft motion is detected.
Each input is filtered to ensure only true transitions are recorded.
This controller also provides a full set of standard programmable peripherals that include two Serial
Communications Interfaces (SCIs); two Serial Peripheral Interfaces (SPIs); and four Quad Timers. Any of
these interfaces can be used as General Purpose Input/Outputs (GPIOs) if that function is not required. A
Flex Controller Area Network (FlexCAN) interface (CAN Version 2.0 B-compliant) and an internal
interrupt controller are also a part of the 56F8335.
1.2.2
56F8135 Features
The 56F8135 includes 64KB of Program Flash, programmable through the JTAG port, and 8KB of Data
RAM. A total of 8KB of Boot Flash is incorporated for easy customer inclusion of field-programmable
software routines that can be used to program the main Program Flash memory area. The Program Flash
memory can be independently bulk erased or erased in pages; Program Flash page erase size is 1KB. The
Boot Flash page erase size is 512 bytes; Boot Flash memory can also be either bulk or page erased.
A key application-specific feature of the 56F8135 is the inclusion of one Pulse Width Modulator (PWM)

these interfaces can be used as General Purpose Input/Outputs (GPIOs) if that function is not required. An
internal interrupt controller is also a part of the 56F8135.
1.3 Award-Winning Development Environment
Processor Expert
TM
(PE) provides a Rapid Application Design (RAD) tool that combines easy-to-use
component-based software application creation with an expert knowledge system.
The CodeWarrior Integrated Development Environment is a sophisticated tool for code navigation,
compiling, and debugging. A complete set of evaluation modules (EVMs) and development system cards
will support concurrent engineering. Together, PE, CodeWarrior and EVMs create a complete, scalable
tools solution for easy, fast, and efficient development.
1.4 Architecture Block Diagram
Note: Features in italics are NOT available in the 56F8135 device and are shaded in the following figures.
The 56F8335/56F8135 architecture is shown in
Figure 1-1
and
Figure 1-2
.
Figure 1-1
illustrates how the
56800E system buses communicate with internal memories and the IPBus Bridge.
Table 1-2
lists the
internal buses in the 56800E architecture and provides a brief description of their function.
Figure 1-2
shows the peripherals and control blocks connected to the IPBus Bridge. The figures do not show the
on-board regulator and power and ground signals. They also do not show the multiplexing between
peripherals or the dedicated GPIOs. Please see
Part 2, Signal/Connection Descriptions,
to see which
signals are multiplexed with those of other peripherals.
Also shown in
Figure 1-2
are connections between the PWM, Timer C and ADC blocks. These
connections allow the PWM and/or Timer C to control the timing of the start of ADC conversions. The
Timer C channel indicated can generate periodic start (SYNC) signals to the ADC to start its conversions.
In another operating mode, the PWM load interrupt (SYNC output) signal is routed internally to the Timer
C input channel as indicated. The timer can then be used to introduce a controllable delay before
generating its output signal. The timer output then triggers the ADC. To fully understand this interaction,
please see the 56F8300 Peripheral User's Manual for clarification on the operation of all three of these
peripherals.

2.2 Signal Pins
After reset, each pin is configured for its primary function (listed first). Any alternate functionality must
be programmed.
EMI is not functional in this package; since only part of the address/data bus is bonded out, use as GPIO
pins.
Note: Signals in italics are NOT available in the 56F8135 device.
If the "State During Reset" lists more than one state for a pin, the first state is the actual reset state. Other
states show the reset condition of the alternate function, which you get if the alternate pin function is
selected without changing the configuration of the alternate peripheral. For example, the A8/GPIOA0 pin
shows that it is tri-stated during reset. If the GPIOA_PER is changed to select the GPIO function of the
pin, it will become an input if no other registers are changed.

Figure 3-1 OCCS Block Diagram
3.2 External Clock Operation
The system clock can be derived from an external crystal, ceramic resonator, or an external system clock
signal. To generate a reference frequency using the internal oscillator, a reference crystal or ceramic
resonator must be connected between the EXTAL and XTAL pins.
3.2.1
Crystal Oscillator
The internal oscillator is designed to interface with a parallel-resonant crystal resonator in the frequency
range specified for the external crystal in
Table 10-15
. A recommended crystal oscillator circuit is shown
in
Figure 3-2
. Follow the crystal supplier's recommendations when selecting a crystal, since crystal
parameters determine the component values required to provide maximum stability and reliable start-up.
The crystal and associated components should be mounted as near as possible to the EXTAL and XTAL
pins to minimize output distortion and start-up stabilization time.

It is also possible to drive the internal oscillator with a ceramic resonator, assuming the overall system
design can tolerate the reduced signal integrity. A typical ceramic resonator circuit is shown in
Figure 3-3
.
Refer to the supplier's recommendations when selecting a ceramic resonator and associated components.
The resonator and components should be mounted as near as possible to the EXTAL and XTAL pins.

Part 4 Memory Map
4.1 Introduction
The 56F8335 and 56F8135 devices are 16-bit motor-control chips based on the 56800E core. These parts
use a Harvard-style architecture with two independent memory spaces for Data and Program. On-chip
RAM and Flash memories are used in both spaces.
This section provides memory maps for:
Program Address Space, including the Interrupt Vector Table
Data Address Space, including the EOnCE Memory and Peripheral Memory Maps
On-chip memory sizes for each device are summarized in
Table 4-1
. Flash memories' restrictions are
identified in the "Use Restrictions" column of
Table 4-1
.
Note: Data Flash and Program RAM are NOT available on the 56F8135 device.

4.2 Program Map
The Program memory map is located in
Table 4-4
. The operating mode control bits (MA and MB) in the
Operating Mode Register (OMR) control the Program memory map. At reset, these bits are set as indicated
in
Table 4-2
.
EXT_BOOT = EMI_MODE = 0 and cannot be changed in the 56F8335 or 56F8135.
After reset, the OMR MA bit can be changed and will have an effect on the P-space memory map, as shown
in
Table 4-3
. Changing the OMR MB bit will have no effect.
Table 4-4
shows the memory map options of the 56F8335/56F8135. The two right columns cannot be
used, since the EMI pins are not provided in the package; therefore, only the Mode 0 column is relevant.
Note: Program RAM is NOT available on the 56F8135 device.

4.3 Interrupt Vector Table
Table 4-5
provides the reset and interrupt priority structure, including on-chip peripherals. The table is
organized with higher-priority vectors at the top and lower-priority interrupts lower in the table. The
priority of an interrupt can be assigned to different levels, as indicated, allowing some control over
interrupt priorities. All level 3 interrupts will be serviced before level 2, and so on. For a selected priority
level, the lowest vector number has the highest priority.
The location of the vector table is determined by the Vector Base Address (VBA) register. Please see
Part
5.6.11
for the reset value of the VBA.
In some configurations, the reset address and COP reset address will correspond to vector 0 and 1 of the
interrupt vector table. In these instances, the first two locations in the vector table must contain branch or
JMP instructions. All other entries must contain JSR instructions.

1. Two words are allocated for each entry in the vector table. This does not allow the full address range to be referenced
from the vector table, providing only 19 bits of address.
2. If the VBA is set to $0200 (or VBA = 0000 for Mode 1, EMI_MODE = 0), the first two locations of the vector table are
the chip reset addresses; therefore, these locations are not interrupt vectors.

4.4 Data Map
Note: Data Flash is NOT available on the 56F8135 device.
4.5 Flash Memory Map
Figure 4-1
illustrates the Flash Memory (FM) map on the system bus.
The Flash Memory is divided into three functional blocks. The Program and boot memories reside on the
Program Memory buses. They are controlled by one set of banked registers. Data Memory Flash resides
on the Data Memory buses and is controlled separately by its own set of banked registers.
The top nine words of the Program Memory Flash are treated as special memory locations. The content of
these words is used to control the operation of the Flash Controller. Because these words are part of the
Flash Memory content, their state is maintained during power-down and reset. During chip initialization,
the content of these memory locations is loaded into Flash Memory control registers, detailed in the Flash
Memory chapter of the 56F8300 Peripheral User Manual. These configuration parameters are located
between $00_FFF7 and $00_FFFF.

4.7 Peripheral Memory Mapped Registers
On-chip peripheral registers are part of the data memory map on the 56800E series. These locations may
be accessed with the same addressing modes used for ordinary Data memory, except all peripheral
registers should be read/written using word accesses only.
Table 4-9
summarizes base addresses for the set of peripherals on the 56F8335 and 56F8135 devices.
Peripherals are listed in order of the base address.
The following tables list all of the peripheral registers required to control or access the peripherals.
Note: Features in italics are NOT available in the 56F8135 device.

4.8 Factory Programmed Memory
The Boot Flash memory block is programmed during manufacturing with a default Serial Bootloader
program. The Serial Bootloader application can be used to load a user application into the Program and
Data Flash(NOT available in the 56F8135) memories of the device. The 56F83xx SCI/CAN Bootloader
User Manual (MC56F83xxBLUM) provides detailed information on this firmware. An application note,
Production Flash Programming (AN1973), details how the Serial Bootloader program can be used to
perform production Flash programming of the on-board Flash memories as well as other potential
methods.
Like all the Flash memory blocks, the Boot Flash can be erased and programmed by the user. The Serial
Bootloader application is programmed as an aid to the end user, but is not required to be used or maintained
in the Boot Flash memory.

Part 5 Interrupt Controller (ITCN)
5.1 Introduction
The Interrupt Controller (ITCN) module is used to arbitrate between various interrupt requests (IRQs), to
signal to the 56800E core when an interrupt of sufficient priority exists, and to what address to jump in
order to service this interrupt.
5.2 Features
The ITCN module design includes these distinctive features:
Programmable priority levels for each IRQ
Two programmable Fast Interrupts
Notification to SIM module to restart clocks out of Wait and Stop modes
Drives initial address on the address bus after reset
For further information, see
Table 4-5
, Interrupt Vector Table Contents.
5.3 Functional Description
The Interrupt Controller is a slave on the IPBus. It contains registers allowing each of the 82 interrupt
sources to be set to one of four priority levels, excluding certain interrupts of fixed priority. Next, all of
the interrupt requests of a given level are priority encoded to determine the lowest numerical value of the
active interrupt requests for that level. Within a given priority level, 0 is the highest priority, while number
81 is the lowest.
5.3.1
Normal Interrupt Handling
Once the ITCN has determined that an interrupt is to be serviced and which interrupt has the highest
priority, an interrupt vector address is generated. Normal interrupt handling concatenates the VBA and the
vector number to determine the vector address. In this way, an offset is generated into the vector table for
each interrupt.
5.3.2
Interrupt Nesting
Interrupt exceptions may be nested to allow an IRQ of higher priority than the current exception to be
serviced. The following tables define the nesting requirements for each priority level.

5.3.3
Fast Interrupt Handling
Fast interrupts are described in the DSP56F800E Reference Manual. The interrupt controller recognizes
fast interrupts before the core does.
A fast interrupt is defined (to the ITCN) by:
1. Setting the priority of the interrupt as level 2, with the appropriate field in the IPR registers
2. Setting the FIMn register to the appropriate vector number
3. Setting the FIVALn and FIVAHn registers with the address of the code for the fast interrupt
When an interrupt occurs, its vector number is compared with the FIM0 and FIM1 register values. If a
match occurs, and it is a level 2 interrupt, the ITCN handles it as a fast interrupt. The ITCN takes the vector
address from the appropriate FIVALn and FIVAHn registers, instead of generating an address that is an
offset from the VBA.
The core then fetches the instruction from the indicated vector adddress and if it is not a JSR, the core starts
its fast interrupt handling.

5.5 Operating Modes
The ITCN module design contains two major modes of operation:
Functional Mode
The ITCN is in this mode by default.
Wait and Stop Modes
During Wait and Stop modes, the system clocks and the 56800E core are turned off. The ITCN will signal
a pending IRQ to the System Integration Module (SIM) to restart the clocks and service the IRQ. An IRQ
can only wake up the core if the IRQ is enabled prior to entering the Wait or Stop mode. Also, the IRQA
and IRQB signals automatically become low-level sensitive in these modes, even if the control register bits
are set to make them falling-edge sensitive. This is because there is no clock available to detect the falling
edge.
A peripheral which requires a clock to generate interrupts will not be able to generate interrupts during Stop
mode. The FlexCAN module can wake the device from Stop mode, and a reset will do just that, or IRQA
and IRQB can wake it up.

5.6 Register Descriptions
A register address is the sum of a base address and an address offset. The base address is defined at the
system level and the address offset is defined at the module level. The ITCN peripheral has 24 registers.

5.6.11.2 Interrupt Vector Base Address (VECTOR BASE ADDRESS)--
Bits 120
The contents of this register determine the location of the Vector Address Table. The value in this register
is used as the upper 13 bits of the interrupt Vector Address Bus (VAB[20:0]). The lower eight bits are
determined based upon the highest-priority interrupt. They are then appended onto VBA before presenting
the full interrupt address to the 56800E core; see
Part 5.3.1
for details.

This value determines which IRQ will be a Fast Interrupt 0. Fast interrupts vector directly to a service
routine based on values in the Fast Interrupt Vector Address registers without having to go to a jump table
first; see
Part 5.3.3
. IRQs used as fast interrupts must be set to priority level 2. Unexpected results will
occur if a fast interrupt vector is set to any other priority. Fast interrupts automatically become the
highest-priority level 2 interrupt, regardless of their location in the interrupt table, prior to being declared
as fast interrupt. Fast Interrupt 0 has priority over Fast Interrupt 1. To determine the vector number of each
IRQ, refer to
Table 4-5

Reset Handshake Timing
The ITCN provides the 56800E core with a reset vector address whenever RESET is asserted. The reset
vector will be presented until the second rising clock edge after RESET is released.
5.7.2
ITCN After Reset
After reset, all of the ITCN registers are in their default states. This means all interrupts are disabled except
the core IRQs with fixed priorities:
Illegal Instruction
SW Interrupt 3
HW Stack Overflow
Misaligned Long Word Access
SW Interrupt 2
SW Interrupt 1
SW Interrupt 0

Part 6 System Integration Module (SIM)
6.1 Introduction
The SIM module is a system catchall for the glue logic that ties together the system-on-chip. It controls
distribution of resets and clocks and provides a number of control features. The system integration module
is responsible for the following functions:
Reset sequencing
Clock generation & distribution
Stop/Wait control
Pull-up enables for selected peripherals
System status registers
Registers for software access to the JTAG ID of the chip
Enforcing Flash security
These are discussed in more detail in the sections that follow.
6.2 Features
The SIM has the following features:
Flash security feature prevents unauthorized access to code/data contained in on-chip Flash memory
Power-saving clock gating for peripheral
Three power modes (Run, Wait, Stop) to control power utilization
-- Stop mode shuts down the 56800E core, system clock, peripheral clock, and PLL operation
-- Stop mode entry can optionally disable PLL and Oscillator (low power vs. fast restart); must be done
explicitly
-- Wait mode shuts down the 56800E core and unnecessary system clock operation
-- Run mode supports full part operation
Controls to enable/disable the 56800E core WAIT and STOP instructions
Calculates base delay for reset extension based upon POR or RESET operations. Reset delay will be 3 x 32
clocks (phased release of reset) for reset, except for POR, which is 2
21
clock cycles.
Controls reset sequencing after reset
Software-initiated reset
Four 16-bit registers reset only by a Power-On Reset usable for general-purpose software control
System Control Register
Registers for software access to the JTAG ID of the chip

Preliminary
6.3 Operating Modes
Since the SIM is responsible for distributing clocks and resets across the chip, it must understand the
various chip operating modes and take appropriate action. These are:
Reset Mode, which has two submodes:
-- POR and RESET operation
The 56800E core and all peripherals are reset. This occurs when the internal POR is asserted or the
RESET pin is asserted.
-- COP reset and software reset operation
The 56800E core and all peripherals are reset. The MA bit within the OMR is not changed. This allows
the software to determine the boot mode (internal or external boot) to be used on the next reset.
Run Mode
This is the primary mode of operation for this device. In this mode, the 56800E controls chip operation.
Debug Mode
The 56800E is controlled via JTAG/EOnCE when in debug mode. All peripherals, except the COP and
PWMs, continue to run. COP is disabled and PWM outputs are optionally switched off to disable any motor
from being driven; see the PWM chapter in the 56F8300 Peripheral User Manual for details.
Wait Mode
In Wait mode, the core clock and memory clocks are disabled. Optionally, the COP can be stopped.
Similarly, it is an option to switch off PWM outputs to disable any motor from being driven. All other
peripherals continue to run.
Stop Mode
When in Stop mode, the 56800E core, memory and most peripheral clocks are shut down. Optionally, the
COP and CAN can be stopped. For lowest power consumption in Stop mode, the PLL can be shut down.
This must be done explicitly before entering Stop mode, since there is no automatic mechanism for this. The
CAN (along with any non-gated interrupt) is capable of waking the chip up from Stop mode, but is not fully
functional in Stop mode.
6.4 Operating Mode Register
Figure 6-1 OMR
The reset state for MB and MA will depend on the Flash secured state. See
Part 4.2
and
Part 7
for detailed
information on how the Operating Mode Register (OMR) MA and MB bits operate in this device. For
additional information on the EX bit, see
Part 4.4
. For all other bits, see the DSP56F800E Reference
Manual.
Note:
The OMR is not a Memory Map register; it is directly accessible in code through the acronym OMR.

6.5.2.4 External Reset (EXTR)--Bit 3
If 1, the EXTR bit indicates an external system reset has occurred. This bit will be cleared by a Power-On
Reset or by software. Writing a 0 to this bit position will set the bit, while writing a 1 to the bit position
will clear it. Basically, when the EXTR bit is 1, the previous system reset was caused by the external
RESET pin being asserted low.
6.5.2.5 Power-On Reset (POR)--Bit 2
When 1, the POR bit indicates a Power-On Reset occurred some time in the past. This bit can be cleared
only by software or by another type of reset. Writing a 0 to this bit will set the bit, while writing a 1 to the
bit position will clear the bit. In summary, if the bit is 1, the previous system reset was due to a Power-On
Reset.

SIM Pull-up Disable Register (SIM_PUDR)
Most of the pins on the chip have on-chip pull-up resistors. Pins which can operate as GPIO can have these
resistors disabled via the GPIO function. Non-GPIO pins can have their pull-ups disabled by setting the
appropriate bit in this register. Disabling pull-ups is done on a peripheral-by-peripheral basis (for pins not
muxed with GPIO). Each bit in the register (see
Figure 6-8
) corresponds to a functional group of pins. See
Table 2-2
to identify which pins can deactivate the internal pull-up resistor.

CLKO Select Register (SIM_CLKOSR)
The CLKO select register can be used to multiplex out any one of the clocks generated inside the clock
generation and SIM modules. The default value is SYS_CLK. This path has been optimized in order to
minimize any delay and clock duty cycle distortion. All other clocks primarily muxed out are for test
purposes only, and are subject to significant phase shift at high frequencies.
The upper four bits of the GPIOB register can function as GPIO, [A23:A20], or as additional clock output
signals. GPIO has priority and is enabled/disabled via the GPIOB_PER. If GPIOB[7:4] are programmed
to operate as peripheral outputs, then the choice between [A23:A20] and additional clock outputs is done
here in the CLKOSR. The default state is for the peripheral function of GPIOB[7:4] to be programmed as
[A23:A20]. This can be changed by altering [A23:A20], as shown in
Figure 6-9
.

GPIO Peripheral Select Register (SIM_GPS)
The GPIO Peripheral Select Register can be used to multiplex out any one of the three alternate peripherals
for GPIOC. The default peripheral is Quad Decoder 1 and Quad Timer B (NOT available in the 56F8135
device); these peripherals work together.
The four I/O pins associated with GPIOC can function as GPIO, Quad Decoder 1/Quad Timer B, or as
SPI 1 signals. GPIO is not the default and is enabled/disabled via the GPIOC_PER, as shown in
Figure 6-10
and
Table 6-2
. When GPIOC[3:0] are programmed to operate as peripheral I/O, then the
choice between decoder/timer and SPI inputs/outputs is made in the SIM_GPS and in conjunction with the
Quad Timer Status and Control Registers (SCR). The default state is for the peripheral function of
GPIOC[3:0] to be programmed as decoder functions. This can be changed by altering the appropriate
controls in the indicated registers.

6.5.10 I/O Short Address Location Register (SIM_ISALH and SIM_ISALL)
The I/O Short Address Location registers are used to specify the memory referenced via the I/O short
address mode. The I/O short address mode allows the instruction to specify the lower six bits of address;
the upper address bits are not directly controllable. This register set allows limited control of the full
address, as shown in
Figure 6-13
.
Note:
If this register is set to something other than the top of memory (EOnCE register space) and the EX bit
in the OMR is set to 1, the JTAG port cannot access the on-chip EOnCE registers, and debug functions
will be affected.

With this register set, an interrupt driver can set the SIM_ISALL register pair to point to its peripheral
registers and then use the I/O Short addressing mode to reference them. The ISR should restore this register
to its previous contents prior to returning from interrupt.
Note:
The default value of this register set points to the EOnCE registers.
Note:
The pipeline delay between setting this register set and using short I/O addressing with the new value
is three cycles.

This field represents the lower 16 address bits of the "hard coded" I/O short address.
6.6 Clock Generation Overview
The SIM uses an internal master clock from the OCCS (CLKGEN) module to produce the peripheral and
system (core and memory) clocks. The maximum master clock frequency is 120MHz. Peripheral and
system clocks are generated at half the master clock frequency and therefore at a maximum 60MHz. The
SIM provides power modes (Stop, Wait) and clock enables (SIM_PCE register, CLK_DIS, ONCE_EBL)
to control which clocks are in operation. The OCCS, power modes, and clock enables provide a flexible
means to manage power consumption.
Power utilization can be minimized in several ways. In the OCCS, crystal oscillator, and PLL may be shut
down when not in use. When the PLL is in use, its prescaler and postscaler can be used to limit PLL and
master clock frequency. Power modes permit system and/or peripheral clocks to be disabled when unused.
Clock enables provide the means to disable individual clocks. Some peripherals provide further controls
to disable unused subfunctions. Refer to
Part 3 On-Chip Clock Synthesis (OCCS)
, and the 56F8300
Peripheral User Manual for further details.
6.7 Power-Down Modes Overview
The 56F8335/56F8135 operate in one of three power-down modes, as shown in
Table 6-3
.
All peripherals, except the COP/watchdog timer, run off the IPBus clock frequency, which is the same as
the main processor frequency in this architecture. The maximum frequency of operation is
SYS_CLK = 60MHz.

Stop
System clocks continue to be generated in
the SIM, but most are gated prior to
reaching memory, core and peripherals.
The only possible recoveries from Stop mode are:
1. CAN traffic (1st message will be lost)
2. Non-clocked interrupts
3. COP reset
4. External reset
5. Power-on reset

6.8 Stop and Wait Mode Disable Function
Figure 6-16 Internal Stop Disable Circuit
The 56800E core contains both STOP and WAIT instructions. Both put the CPU to sleep. For lowest
power consumption in Stop mode, the PLL can be shut down. This must be done explicitly before entering
Stop mode, since there is no automatic mechanism for this. When the PLL is shut down, the 56800E
system clock must be set equal to the oscillator output.
Some applications require the 56800E STOP and WAIT instructions to be disabled. To disable those
instructions, write to the SIM control register (SIM_CONTROL), described in
Part 6.5.1
. This procedure
can be on either a permanent or temporary basis. Permanently assigned applications last only until their
next reset.
6.9 Resets
The SIM supports four sources of reset. The two asynchronous sources are the external RESET pin and
the Power-On Reset (POR). The two synchronous sources are the software reset, which is generated within
the SIM itself by writing to the SIM_CONTROL register, and the COP reset.
Reset begins with the assertion of any of the reset sources. Release of reset to various blocks is sequenced
to permit proper operation of the device. A POR reset is first extended for 2
21
clock cycles to permit
stabilization of the clock source, followed by a 32 clock window in which SIM clocking is initiated. It is
then followed by a 32 clock window in which peripherals are released to implement Flash security, and,
finally, followed by a 32 clock window in which the core is initialized. After completion of the described
reset sequence, application code will begin execution.
Resets may be asserted asynchronously, but are always released internally on a rising edge of the system
clock.

Operation with Security Enabled

Freescale Semiconductor
115
Preliminary
Part 7 Security Features
The 56F8335/56F8135 offer security features intended to prevent unauthorized users from reading the
contents of the Flash Memory (FM) array. The Flash security consists of several hardware interlocks that
block the means by which an unauthorized user could gain access to the Flash array.
However, part of the security must lie with the user's code. An extreme example would be user's code that
dumps the contents of the internal program, as this code would defeat the purpose of security. At the same
time, the user may also wish to put a "backdoor" in his program. As an example, the user downloads a
security key through the SCI, allowing access to a programming routine that updates parameters stored in
another section of the Flash.
7.1 Operation with Security Enabled
Once the user has programmed the Flash with his application code, the device can be secured by
programming the security bytes located in the FM configuration field, which occupies a portion of the FM
array. These non-volatile bytes will keep the part secured through reset and through power-down of the
device. Only two bytes within this field are used to enable or disable security. Refer to the Flash Memory
section in the 56F8300 Peripheral User Manual for the state of the security bytes and the resulting state
of security. When Flash security mode is enabled in accordance with the method described in the Flash
Memory module specification, the device will disable the core EOnCE debug capabilities. Normal
program execution is otherwise unaffected.
7.2 Flash Access Blocking Mechanisms
The 56F8335/56F8135 have several operating functional and test modes. Effective Flash security must
address operating mode selection and anticipate modes in which the on-chip Flash can be compromised
and read without explicit user permission. Methods to block these are outlined in the next subsections.
7.2.1
Forced Operating Mode Selection
At boot time, the SIM determines in which functional modes the device will operate. These are:
Unsecured Mode
Secure Mode (EOnCE disabled)
When Flash security is enabled as described in the Flash Memory module specification, the device will
disable the EOnCE debug interface.
56F8335 Technical Data, Rev. 1
116
Freescale Semiconductor
Preliminary
7.2.2
Disabling EOnCE Access
On-chip Flash can be read by issuing commands across the EOnCE port, which is the debug interface for
the 56800E core. The TRST, TCLK, TMS, TDO, and TDI pins comprise a JTAG interface onto which the
EOnCE port functionality is mapped. When the device boots, the chip-level JTAG TAP (Test Access Port)
is active and provides the chip's boundary scan capability and access to the ID register.
Proper implementation of Flash security requires that no access to the EOnCE port is provided when
security is enabled. The 56800E core has an input which disables reading of internal memory via the
JTAG/EOnCE. The FM sets this input at reset to a value determined by the contents of the FM security
bytes.
7.2.3
Flash Lockout Recovery
If a user inadvertently enables Flash security on the device, a built-in lockout recovery mechanism can be
used to reenable access to the device. This mechanism completely reases all on-chip Flash, thus disabling
Flash security. Access to this recovery mechanism is built into CodeWarrior via an instruction in memory
configuration (.cfg) files. Add, or uncomment the following configuration command:
unlock_flash_on_connect 1
For more information, please see CodeWarrior MC56F83xx/DSP5685x Family Targeting Manual.
The LOCKOUT_RECOVERY instruction has an associated 7-bit Data Register (DR) that is used to
control the clock divider circuit within the FM module. This divider, FM_CLKDIV[6:0], is used to control
the period of the clock used for timed events in the FM erase algorithm. This register must be set with
appropriate values before the lockout sequence can begin. Refer to the JTAG section of the 56F8300
Peripheral User Manual for more details on setting this register value.
The value of the JTAG FM_CLKDIV[6:0] will replace the value of the FM register FMCLKD that divides
down the system clock for timed events, as illustrated in
Figure 7-1
. FM_CLKDIV[6] will map to the
PRDIV8 bit, and FM_CLKDIV[5:0] will map to the DIV[5:0] bits. The combination of PRDIV8 and DIV
must divide the FM input clock down to a frequency of 150kHz-200kHz. The "Writing the FMCLKD
Register" section in the Flash Memory chapter of the 56F8300 Peripheral User Manual gives specific
equations for calculating the correct values.
Flash Access Blocking Mechanisms
56F8335 Technical Data, Rev. 1
Freescale Semiconductor
117
Preliminary
Figure 7-1 JTAG to FM Connection for Lockout Recovery
Two examples of FM_CLKDIV calculations follow.
EXAMPLE 1: If the system clock is the 8MHz crystal frequency because the PLL has not been set up,
the input clock will be below 12.8MHz, so PRDIV8 = FM_CLKDIV[6] = 0. Using the following equation
yields a DIV value of 19 for a clock of 200kHz, and a DIV value of 20 for a clock of 190kHz. This
translates into an FM_CLKDIV[6:0] value of $13 or $14, respectively.
EXAMPLE 2: In this example, the system clock has been set up with a value of 32MHz, making the FM
input clock 16MHz. Because that is greater than 12.8MHz, PRDIV8 = FM_CLKDIV[6] = 1. Using the
following equation yields a DIV value of 9 for a clock of 200kHz, and a DIV value of 10 for a clock of
181kHz. This translates to an FM_CLKDIV[6:0] value of $49 or $4A, respectively.
Once the LOCKOUT_RECOVERY instruction has been shifted into the instruction register, the clock
divider value must be shifted into the corresponding 7-bit data register. After the data register has been
updated, the user must transition the TAP controller into the RUN-TEST/IDLE state for the lockout
sequence to commence. The controller must remain in this state until the erase sequence has completed.
For details, see the JTAG Section in the 56F8300 Peripheral User Manual.

Note:
When the lockout recovery sequence has completed, the user must reset both the JTAG TAP controller
(by asserting TRST) and the device (by asserting external chip reset) to return to normal unsecured
operation.
7.2.4
Product Analysis
The recommended method of unsecuring a programmed device for product analysis of field failures is via
the backdoor key access. The customer would need to supply Technical Support with the backdoor key
and the protocol to access the backdoor routine in the Flash. Additionally, the KEYEN bit that allows
backdoor key access must be set.
An alternative method for performing analysis on a secured hybrid controller would be to mass-erase and
reprogram the Flash with the original code, but to modify the security bytes.
To insure that a customer does not inadvertently lock himself out of the device during programming, it is
recommended that he program the backdoor access key first, his application code second, and the security
bytes within the FM configuration field last.

Manual and contains only chip-specific information. This information supercedes the generic information
in the 56F8300 Peripheral User Manual.
8.2 Memory Maps
The width of the GPIO port defines how many bits are implemented in each of the GPIO registers. Based
on this and the default function of each of the GPIO pins, the reset values of the GPIOx_PUR and
GPIOx_PER registers change from port to port. Tables
4-29
through
4-34
define the actual reset values of
these registers.

Part 10 Specifications
10.1 General Characteristics
The 56F8335/56F8135 are fabricated in high-density CMOS with 5V-tolerant TTL-compatible digital
inputs. The term "5V-tolerant" refers to the capability of an I/O pin, built on a 3.3V-compatible process
technology, to withstand a voltage up to 5.5V without damaging the device. Many systems have a mixture
of devices designed for 3.3V and 5V power supplies. In such systems, a bus may carry both 3.3V- and
5V-compatible I/O voltage levels (a standard 3.3V I/O is designed to receive a maximum voltage of 3.3V
10% during normal operation without causing damage). This 5V-tolerant capability therefore offers the
power savings of 3.3V I/O levels combined with the ability to receive 5V levels without damage.
Absolute maximum ratings in
Table 10-1
are stress ratings only, and functional operation at the maximum
is not guaranteed. Stress beyond these ratings may affect device reliability or cause permanent damage to
the device.
Note: All specifications meet both Automotive and Industrial requirements unless individual
specifications are listed.
Note: The 56F8135 device is guaranteed to 40MHz and specified to meet Industrial requirements only.
Note: The 56F8135 device is specified to meet Industrial requirements only; CAN is NOT available on the
56F8135 device.
CAUTION
This device contains protective circuitry to guard against damage
due to high static voltage or electrical fields. However, normal
precautions are advised to avoid application of any voltages higher
than maximum-rated voltages to this high-impedance circuit.
Reliability of operation is enhanced if unused inputs are tied to an
appropriate voltage level.

Preliminary
1. Theta-JA determined on 2s2p test boards is frequently lower than would be observed in an application. Determined on 2s2p ther-
mal test board.
2. Junction to ambient thermal resistance, Theta-JA (R
JA
) was simulated to be equivalent to the JEDEC specification JESD51-2
in a horizontal configuration in natural convection. Theta-JA was also simulated on a thermal test board with two internal planes
(2s2p, where "s" is the number of signal layers and "p" is the number of planes) per JESD51-6 and JESD51-7. The correct name
for Theta-JA for forced convection or with the non-single layer boards is Theta-JMA.
3. Junction to case thermal resistance, Theta-JC (R
JC
), was simulated to be equivalent to the measured values using the cold
plate technique with the cold plate temperature used as the "case" temperature. The basic cold plate measurement technique is
described by MIL-STD 883D, Method 1012.1. This is the correct thermal metric to use to calculate thermal performance when
the package is being used with a heat sink.
4. Thermal Characterization Parameter, Psi-JT (
JT
), is the "resistance" from junction to reference point thermocouple on top cen-
ter of case as defined in JESD51-2.
JT
is a useful value to use to estimate junction temperature in steady-state customer en-
vironments.
5. Junction temperature is a function of on-chip power dissipation, package thermal resistance, mounting site (board) temperature,
ambient temperature, air flow, power dissipation of other components on the board, and board thermal resistance.
6. See
Part 12.1
for more details on thermal design considerations.

TA = Ambient Temperature

Figure 10-21 ADC Absolute Error Over Processing and Temperature Extremes Before
and After Calibration for VDC
in
= 0.60V and 2.70V
Note: The absolute error data shown in the graphs above reflects the effects of both gain error and offset
error. The data was taken on 15 parts: three each from four processing corner lots as well as three from one
nominally processed lot, each at three temperatures: -40C, 27C, and 150C (giving the 45 data points
shown above), for two input DC voltages: 0.60V and 2.70V. The data indicates that for the given
population of parts, calibration significantly reduced (by as much as 39%) the collective variation (spread)
of the absolute error of the population. It also significantly reduced (by as much as 80%) the mean

Although not guaranteed, it is believed that calibration will produce results similar to those shown above
for any population of parts including those which represent processing and temperature extremes.

10.16 Equivalent Circuit for ADC Inputs
Figure 10-22
illustrates the ADC input circuit during sample and hold. S1 and S2 are always open/closed
at the same time that S3 is closed/open. When S1/S2 are closed & S3 is open, one input of the sample and
hold circuit moves to V
REFH
- V
REFH
/ 2, while the other charges to the analog input voltage. When the
switches are flipped, the charge on C1 and C2 are averaged via S3, with the result that a single-ended
analog input is switched to a differential voltage centered about V
REFH
- V
REFH
/ 2. The switches switch
on every cycle of the ADC clock (open one-half ADC clock, closed one-half ADC clock). Note that there
are additional capacitances associated with the analog input pad, routing, etc., but these do not filter into
the S/H output voltage, as S1 provides isolation during the charge-sharing phase.
One aspect of this circuit is that there is an on-going input current, which is a function of the analog input
voltage, V
REF
and the ADC clock frequency.

10.17 Power Consumption
This section provides additional detail which can be used to optimize power consumption for a given
application.
Power consumption is given by the following equation:
A, the internal [static component], is comprised of the DC bias currents for the oscillator, leakage current,
PLL, and voltage references. These sources operate independently of processor state or operating
frequency.
B, the internal [state-dependent component], reflects the supply current required by certain on-chip
resources only when those resources are in use. These include RAM, Flash memory and the ADCs.
Total power =
A: internal [static component]
+B: internal [state-dependent component]
+C: internal [dynamic component]
+D: external [dynamic component]
+E: external [static]

C, the internal [dynamic component], is classic C*V
2
*F CMOS power dissipation corresponding to the
56800E core and standard cell logic.
D, the external [dynamic component], reflects power dissipated on-chip as a result of capacitive loading
on the external pins of the chip. This is also commonly described as C*V
2
*F, although simulations on two
of the IO cell types used on the device reveal that the power-versus-load curve does have a non-zero
Y-intercept.
Power due to capacitive loading on output pins is (first order) a function of the capacitive load and
frequency at which the outputs change.
Table 10-24
provides coefficients for calculating power dissipated
in the IO cells as a function of capacitive load. In these cases:
Total Power =
((Intercept +Slope*Cload)*frequency/10MHz)
where:
Summation is performed over all output pins with capacitive loads
Total Power is expressed in mW
Cload is expressed in pF
Because of the low duty cycle on most device pins, power dissipation due to capacitive loads was found
to be fairly low when averaged over a period of time.
E, the external [static component], reflects the effects of placing resistive loads on the outputs of the
device. Sum the total of all V
2
/R or IV to arrive at the resistive load contribution to power. Assume V =
0.5 for the purposes of these rough calculations. For instance, if there is a total of eight PWM outputs
driving 10mA into LEDs, then P = 8*.5*.01 = 40mW.
In previous discussions, power consumption due to parasitics associated with pure input pins is ignored,
as it is assumed to be negligible.

Thermal Design Considerations

Part 12 Design Considerations
12.1 Thermal Design Considerations
An estimation of the chip junction temperature, T
J
, can be obtained from the equation:
T
J
= T
A
+ (R
J
x
P
D
)
where:
The junction-to-ambient thermal resistance is an industry-standard value that provides a quick and easy
estimation of thermal performance. Unfortunately, there are two values in common usage: the value
determined on a single-layer board and the value obtained on a board with two planes. For packages such
as the PBGA, these values can be different by a factor of two. Which value is closer to the application
depends on the power dissipated by other components on the board. The value obtained on a single-layer
board is appropriate for the tightly packed printed circuit board. The value obtained on the board with the
internal planes is usually appropriate if the board has low-power dissipation and the components are well
separated.
When a heat sink is used, the thermal resistance is expressed as the sum of a junction-to-case thermal
resistance and a case-to-ambient thermal resistance:
R
JA
= R
JC
+ R
CA
where:
R
JC
is device-related and cannot be influenced by the user. The user controls the thermal environment to
change the case-to-ambient thermal resistance, R
CA
. For instance, the user can change the size of the heat
sink, the air flow around the device, the interface material, the mounting arrangement on printed circuit
board, or change the thermal dissipation on the printed circuit board surrounding the device.
To determine the junction temperature of the device in the application when heat sinks are not used, the
Thermal Characterization Parameter (
JT
) can be used to determine the junction temperature with a
measurement of the temperature at the top center of the package case using the following equation:
T
J
= T
T
+ (
JT
x P
D
)
where:
T
A
= Ambient temperature for the package (
o
C)
R
J
= Junction-to-ambient thermal resistance (
o
C/W)
P
D
= Power dissipation in the package (W)
R
JA
= Package junction-to-ambient thermal resistance C/W
R
JC
= Package junction-to-case thermal resistance C/W
R
CA
= Package case-to-ambient thermal resistance C/W
T
T
= Thermocouple temperature on top of package (
o

JT
= Thermal characterization parameter (

C)/W
P
D
= Power dissipation in package (W)

thermocouple epoxied to the top center of the package case. The thermocouple should be positioned so
that the thermocouple junction rests on the package. A small amount of epoxy is placed over the
thermocouple junction and over about 1mm of wire extending from the junction. The thermocouple wire
is placed flat against the package case to avoid measurement errors caused by cooling effects of the
thermocouple wire.
When heat sink is used, the junction temperature is determined from a thermocouple inserted at the
interface between the case of the package and the interface material. A clearance slot or hole is normally
required in the heat sink. Minimizing the size of the clearance is important to minimize the change in
thermal performance caused by removing part of the thermal interface to the heat sink. Because of the
experimental difficulties with this technique, many engineers measure the heat sink temperature and then
back-calculate the case temperature using a separate measurement of the thermal resistance of the
interface. From this case temperature, the junction temperature is determined from the junction-to-case
thermal resistance.
12.2 Electrical Design Considerations
Use the following list of considerations to assure correct operation of the 56F8335/56F8135:
Provide a low-impedance path from the board power supply to each V
DD
pin on the device, and from the
board ground to each V
SS
(GND) pin
The minimum bypass requirement is to place six 0.010.1
F capacitors positioned as close as possible to
the package supply pins. The recommended bypass configuration is to place one bypass capacitor on each
of the V
DD
/V
SS
pairs, including V
DDA
/V
SSA.
Ceramic and tantalum capacitors tend to provide better
performance tolerances.
Ensure that capacitor leads and associated printed circuit traces that connect to the chip V
DD
and V
SS
(GND)
pins are less than 0.5 inch per capacitor lead
Use at least a four-layer Printed Circuit Board (PCB) with two inner layers for V
DD
and V
SS
Bypass the V
DD
and V
SS
layers of the PCB with approximately 100
F, preferably with a high-grade
capacitor such as a tantalum capacitor
CAUTION
This device contains protective circuitry to guard
against damage due to high static voltage or electrical
fields. However, normal precautions are advised to
avoid application of any voltages higher than
maximum-rated voltages to this high-impedance circuit.
Reliability of operation is enhanced if unused inputs are
tied to an appropriate voltage level.

Preliminary
Because the device's output signals have fast rise and fall times, PCB trace lengths should be minimal
Consider all device loads as well as parasitic capacitance due to PCB traces when calculating capacitance.
This is especially critical in systems with higher capacitive loads that could create higher transient currents
in the V
DD
and V
SS
circuits.
Take special care to minimize noise levels on the V
REF
, V
DDA
and V
SSA
pins
Designs that utilize the TRST pin for JTAG port or OnCE module functionality (such as development or
debugging systems) should allow a means to assert TRST whenever RESET is asserted, as well as a means
to assert TRST independently of RESET. Designs that do not require debugging functionality, such as
consumer products, should tie these pins together.
Because the Flash memory is programmed through the JTAG/OnCE port, the designer should provide an
interface to this port to allow in-circuit Flash programming
12.3 Power Distribution and I/O Ring Implementation
Figure 12-1
illustrates the general power control incorporated in the 56F8335/56F8135. This chip
contains two internal power regulators. One of them is powered from the V
DDA_OSC_PLL
pin and cannot
be turned off. This regulator controls power to the internal clock generation circuitry. The other regulator
is powered from the V
DD_IO
pins and provides power to all of the internal digital logic of the core, all
peripherals and the internal memories. This regulator can be turned off, if an external V
DD_CORE
voltage
is externally applied to the V
CAP
pins.
In summary, the entire chip can be supplied from a single 3.3 volt supply if the large core regulator is
enabled. If the regulator is not enabled, a dual supply 3.3V/2.5V configuration can also be used.
Notes:
Flash, RAM and internal logic are powered from the core regulator output
