No.A0548-3/21

Ports

• Input / Output Ports

: 5 ports (28 terminals)

Data direction programmable in nibble units

: 1 port (8 terminals)

(If the N-ch open drain output is selected by option, the corresponding port data can be read in output mode.)

Data direction programmable for each bit individually

: 4 ports (20 terminals)

AD Converter

• 4-channels × 8-bit AD converters

Serial Interfaces

• IIC-bus compliant serial interface (Multi-master type)

Consists of a single built-in circuit with two I/O channels. The two data lines and two clock lines can be connected

internally.

• Synchronous 8-bit serial interface

UART

• Full duplex

• 7/8/9 bit data bits selectable

• 1 stop bit

• Built-in baudrate generator

PWM Output

• 3 channels × 7-bit PWM

Timer

• Timer 0: 16-bit timer/counter

With 2-bit prescaler + 8-bit programmable prescaler

Mode 0: Two 8-bit timers with a programmable prescaler

Mode 1: 8-bit timer with a programmable prescaler + 8-bit counter

Mode 2: 16-bit timer with a programmable prescaler

Mode 3: 16-bit counter

The resolution of timer is 1 tCYC.

• Timer 1: 16-bit timer/PWM

Mode 0: Two 8-bit timers

Mode 1: 8-bit timer + 8-bit PWM

Mode 2: 16-bit timer

Mode 3: Variable bit PWM (9 to 16 bits)

In mode 0/1, the resolution of Timer1/PWM is 1 tCYC

In mode 2/3, the resolution is selectable by program; tCYC or 1/2 tCYC

• Base timer

Generate every 500ms overflow for a clock application

(using 32.768kHz crystal oscillation for the base timer clock)

Generate every 976µs, 3.9ms, 15.6ms, 62.5ms overflow

(using 32.768kHz crystal oscillation for the base timer clock)

Clock for the base timer is selectable from 32.768kHz crystal oscillation, system clock or programmable prescaler

output of Timer 0

Remote Control Receiver Circuit (connected to the P73/INT3/T0IN terminal)

• Noise rejection function

• Polarity switching

Watchdog Timer

External RC circuit is required

Interrupt or system reset is activated when the timer overflows

ROM Correction Function
