- Base timer
1. The clock signal can be selected from any of the following: sub-clock (32.768kHz crystal oscillator), system
clock, and prescaler output for timer 0.
2. Interrupts can be selected to occur at one of five different times.

(6) SIO
- SIO0: 8 bit synchronous serial interface
1. LSB first/MSB first function available
2. Internal 8-bit baud-rate generator (maximum transmit clock period 4/3 T
CYC
)
3. Continuous automatic data communications (1 - 256 bits)
- SIO1: 8 bit asynchronous/synchronous serial interface
Mode 0: Synchronous 8 bit serial IO (2-wire or 3-wire, transmit clock 2 - 512 T
CYC
)
Mode 1: Asynchronous serial IO (half duplex, 8 data bits, 1 stop bit, baud rate 8 - 2048 T
CYC
)
Mode 2: Bus mode 1 (start bit, 8 data bits, transmit clock 2 - 512 T
CYC
)
Mode 3: Bus mode 2 (start detection, 8 data bits, stop detection)

(7) AD converter
- 8-bits
3-channels
(8) PWM
- 2 channel synchronous variable 12 bit PWM

(9) Parallel interface
- RS, RD , WR , CS0 - CS2 Outputs (reversible polarity)
- read/write possible in 1 T
CYC

(10) Remote control receiver circuit (connected to P73/INT3/T0IN terminal)
- Noise rejection function (noise rejection filter time constant can selected from 1/32/128 T
CYC
)

(11) Watchdog timer
- The watchdog timer period set by external RC.
- Watchdog timer can be set to produce interrupt, system reset

(12) Interrupts
- 16-source, 10-vectored interrupts:
1. Three level (low, high and highest) multiple interrupts are supported. During interrupt handling, an equal or
lower level interrupt request is refused.
2. If interrupt requests to two or more vector addresses occur at once, the higher level interrupt takes precedence.
In the case of equal priority levels, the vector with the lowest address takes precedence.
No.

(16) Standby function
- HALT mode
HALT mode is used to reduce power consumption. Program execution is stopped. Peripheral circuits still operate.
1. Oscillation circuits are not stopped automatically
2. Release on system reset
- HOLD mode
HOLD mode is used to reduce the power dissipation. Both program execution and peripheral circuits are stopped.
1. CF, RC and crystal oscillation circuits stop automatically
2. Release occurs on any of the following conditions
input to the reset pin goes low
a specified level is input to at least one of INT0, INT1, INT2, INT4, INT5
an interrupt condition arises at port 0

- X'tal HOLD mode
X'tal HOLD mode is used to reduce power consumption. Program execution is stopped. All peripheral circuits
except the base timer are stopped.
1. CF and RC oscillation circuits stop automatically
2. Crystal oscillator is maintained in its state at HOLD mode inception.
3. Release occurs on any of the following conditions
input to the reset pin goes low
a specified level is input to at least one of INT0, INT1, INT2, INT4, INT5
an interrupt condition arises at port 0
an interrupt condition arises at the base-timer
