4. I/O PORT
SNL310 provides totally 64 I/O pins (P2.0~P2.15, P3.0~P3.15, P4.0~P4.15, and
P5.0~P5.15). The input pull high resistor of each pin can be programmed by Port
Pull-High Register and the direction of I/O port is selected by Port Direction Register.
The Port2 (P2.0~P2.15) and Port3 (P3.0~P3.15) can wake the chip up from the stop
mode and watch mode.
These 64 programmable I/O pins provides not only a simply input/output function but
also flexible configuration. It can be configured to be an 8-bit microprocessor interface
to drive external devices, such as mask ROM, Flash and SRAM and LCD driver.
Furthermore, the pins "TxD" and "RxD" are shared with P3.0 and P3.1.
The internal structure of I/O pins is showed in Figure-2.

In some applications (e.g., Infra Red, IR), an output port needs to be modulated a carry
signal. In the cases, the routine of modulation will occupy too many CPU computations.
Thus, a modulation circuit is built in chip to reduce CPU's loading,

The modulation function will be active when the control bit "IREN" set to "1". And
setting timer2 can generate the frequency of carry signal.
5. TIMER/COUNTER
SNL310 provides three 8-bit timer/event counters (T0/T1/T2). Each timer is 8-bit
binary up-count timer with pre-scalar and auto-reload function. Timer 0 (T0) was
used when voice playing, so user should avoid to use T0.

6. Real Time Clock (RTC)
To realize the watch function, 0.25s RTC (real time clock) is built in the chip. The real
time clock has two clock sources. One is from system clock (16MHZ) and another one
is from low-speed clock source (32768HZ). Once the RTC function is enabled, the
RTC circuit will generate an interrupt request per 0.25 second.
If chip is in power-down mode and interrupt enable is active for RTC, then chip will be
wake-up from power-down mode per 0.25 second.
7. DA & PWM
To play out voices, SNL310 contains two different solutions for the user's
applications, DAC and PWM. The user can choose one of these two solutions in this
design. Only one function can be activated at one time.
7.1 DAC
A 10-bit current type digital-to-analog converter is built-in SNL310. The relationship
between input digital data and output analog current signal is listed in the following
table. Also, the recommended application circuit is illustrated as follows.

7.2 PWM
A PWM (pulse width modulation) circuit is built-in SNL310. PWM can convert input
digital data into pulse trains with suitable different pulse width. The maximum
resolution of PWM is 10 bits. Two huge output stage circuits are included in SNL310.
Both of them are capable of driving speaker directly. The recommended application
circuit is as follows.

8. EXTENSION BUS
SNL310 totally provides 64 I/O pins, those I/O pins can be configured to be address,
data and control signal of extension bus except P2.0~P2.15 are the dedicated general
I/O pins. Table-1 shows the relation among P3.5~P3.15, P4.0~P4.15, P5.0~P5.7 and
I/O pins.

SNL310 provides four chip select pins for external devices, each chip select pin can be
connected to memory device or LCD driver. Besides, all the address, data and control
pins of extension bus are shared with general I/O pins. Normally, the default setting is
general I/O pins for extension bus. User just need to set the enable control bit of
extension bus then all the corresponding I/O pins will switch to be extension bus
automatically.
8.1 Extension Bus for External Memory Device
SNL310 provides two access modes for external memory device. One
is 8-bit mode
and another one is 16-bit mode. User has to use 16-bit mode if executed user's
program is from external memory. Most important of all, SNL310 only can execute
user's program from the first external device. So user has to connect Mask ROM or
Flash which already burn-in user's program to the "CS1"

Figure-6
Figure-5 shows the hardware connection for 8-bit/16-bit mode for external memory
accessing. The memory size calculation of each external memory device is a little
difference between 8-bit and 16-bit mode because of
the address pin "A[22]".
In 16-bit mode, "A[22]" pin can be connected to external memory. And chip will read
one byte data from external memory twice to get a complete 16-bit instruction code or
data. So the maximum memory size can support up to 64M bits of each device.
In 8-bit mode, considering the memory mapping issue, user can't connected "A[22]"
pin to external memory. So the maximum memory size can support up to 32M bits.
Figure-6 figures out how the data be read from external memory in 8-bit/16-bit mode.
However, all the data access from external memory is treated as RAM accessing
except executes user's program from external memory. User should use indirection
RAM access instruction to read data from external memory. Therefore, each chip
selects pin representing a RAM bank in memory allocation of SNL310.

16-Bit LCD Controller
The addressing capacity of each external device is showed in Table-2. The memory
allocation of each bank is 64K words and the addressing region of each device totally
includes
64 banks except 1
st
device. In fact, the RAM bank of 1
st
device is shared with
internal memory of SNL310, so there are only 56 banks in the first device. In another
hand, user can not use full memory location in the first device. The actual addressing
capacity of first device is less than 64M bits (64M bits 8M bits) = 56M bits in 16-bit
mode.

9. UART INTERFACE
The built-in UART supports the serial data transmission. SNL310 provides data
phase auto-clock calibration function. The RxD pin and TxD pin are shared with P3.0
& P3.1, and user can switch P3.0 and P3.1 to be RxD and TxD by configuring the
RxD/TxD enable bit of UARTC register. User can configure the baud rate of UART
from 1200bps to 115200bps just by using the single crystal system (16MHZ crystal).
All the clock base of baud rate is counting by Timer2.
10. LCD DRIVER INTERFACE
10.1 8-Bit Interface
The extension bus of SNL310 supports not only external memory device but also 8-bit
8080/6800 microprocessor interface for external LCD controller which already built-in
LCD display RAM. User should enable extension bus before driving external LCD
driver, and define the chip select pin you used to connect to LCD driver in EBC
register.
In 8-bit interface LCD controller, LCD display data is stored in LCD driver. Any change
of LCD display is sent out to external LCD driver's RAM by addressing different SRAM
space. The interface emulates the 8080/6800-series interface to speed up the
interface data moving processing.
Figure-11 and Figure-12 are the timing diagrams between SNL310 and LCD driver by using
8-bit 8080/6800 interface.

In SNL310, the interface with external 8-bit mode LCD driver is shared with extension
bus. When LCD driver connected to SNL310, chip will allocate a memory area for LCD
driver and the size of this memory area will depend on unit size of each external device.
So it is easy to configure LCD driver and read/write data to/from LCD driver. Figure-13
and Figure-14 show out the system connection of 808/6800 LCD interfaces between
SNL310 and LCD driver.

10.2 1-Bit Interface
SNL310 supports not just 8-bit interface but also 1-bit interface LCD driver. For this
kind LCD driver doesn't include display RAM. All the display data is stored in host CPU.
So host CPU has to specify a dedicate interface to drive LCD driver. Beside the
interface, SNL310 reserves
the last 2K words RAM (0x0800~0x0FFF) for stored the
display data, then interface circuit will send accurate signal to LCD driver
automatically.
P3.6~P3.10 can be configured to be 1-bit interface for LCD driver just by property
setting control register. Table-3 shows the relation between P3.6~P3.10 and LCD
driver interface.

10.3 LCD RAM Assignment
Generally, those 1-bit interface LCD drivers don't built-in the LCD display RAM. All the
display data have been stored in CPU side. The SNL310 already built-in totally 4K
words RAM, so user can set a property value of LCD RAM start address (LRSA)
register to assign a RAM location for LCD display data. The start address setting
formula is shown as bellow:
Calculating formula of start address
If SEG number divided by 16
4096-(SEG numbe/16)*COM number => for B/W
4096-(SEG numbe/16)*COM number*2 => for 4 gray levels
If SEG number can't divided by 16
4096-((SEG numbe/16)+1)*COM number => for B/W
4096-((SEG numbe/16)+1)*COM number*2 => for 4 gray levels
Once upon user set the start address of LCD display RAM and active this interface
function, chip will send the display data out to external LCD driver at the right time.

10.5 LCD Interface Configuration
There are thee control registers (LCDC, COMN and SEGN) to configure hardware to
generate correct interface signal for LCD driver. The COMN and SEGN register are
used to specify how many common and segment number of LCD display. And the
LCDC register is the most important configuration register for this interface. For the
detail setting is showed as bellow:

NOTE:
1. The real Frame Rate
- For B/W display = FRate value/2
- For 2 gray level = FRate value/4
- For 4 gray level = FRate value/6
2. Pre-Scalar calculation formula
Formula:
Divider value * 2
15
> SEG number * (COM number+1) * 2
(pre-scalar value+1)
Example:
LCD display = 80com X 160seg (B/W display)
Frame Rate = 64
2 * 2
15
>160*(80+1)*2
(pre-scalar value+1)
Pre-scalar < = 1 (0x001)
