? Only 49 instructions
? 4K x 13 bits on chip EPROM/ROM
? All ROM/EPROM area GOTO/FGOTO instruction
? All ROM/EPROM area subroutine CALL/FCALL instruction
? Totally 272 x 8 bits on chip general purpose registers (SRAM):
- 144 bytes general purpose register
- 128 bytes on-chip data RAM
? 8-level deep hardware stack
? Direct, indirect addressing modes for data accessing
? 8-bit real time clock/counter (Timer0) with 8-bit programmable prescaler
? Four sets of 8-bit auto reload counter/timer can be used as IROUT/PWM generator or interrupt sources
- Counter 1: independent counter
- Counter 2, High Pulse Width Timer, and Low Pulse Width Timer shared with IR function
? One IROUT/PWM generator
? LCD driver with 4(common) x 32(segment) pixels; 1/3, 1/2 bias and 1/4, 1/3, 1/2 duty selection
? 3 channels of 15-bit resolution Resistor to Frequency Converter (RFC) output
? Internal Power-on Reset (POR)
? Built-in Low Voltage Detector (LVD) for Brown-out Reset (BOR)
? Power-up Reset Timer (PWRT) and Oscillator Start-up Timer(OST)
? On chip Watchdog Timer (WDT) with internal oscillator and soft-ware watch-dog enable/disable control
? Four I/O ports IOA, IOB, IOC and IOD with independent direction control
? Soft-ware I/O pull-high/pull-down or open-drain control
? Seven internal interrupt source: Timer0, Counter1, Counter2, High-pulse width timer, Low-pulse width timer,
RFC and Fs divider; Three external interrupt source: INT0 pin, INT1 pin and Port B / Port D input status change
? Wake-up from SLEEP/IDLE by Port B/Port D input change
? Operation modes:
- Normal mode : CPU operate on high frequency main-oscillator
