Data direction programmable for each bit individually: 3 ports (15 terminals) AD Converter • 4 channels×6-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. 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. • Base Timer Generate every 500ms overflow for a clock application (using 32.768kHz crystal oscillation for the base timer clock) Generate every 976 μs, 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 Max 128 bytes / 2 addresses |
