selected by programming option:
150 μs,20ms
ꢀ 8-bit real time clock/counter(RTCC)
with 8-bit programmable prescaler
ꢀ On-chip RC oscillator based Watchdog
Timer(WDT) can be operated freely
ꢀ 20 I/O pins with their own independent
direction control
On chip memory system includes 2.0 K
words of ROM, and 80 bytes of static
RAM.
2. Features
