FEATURES
Total 8 channel 10bit AD converter with ±2LSB resolution
All instructions are single cycle except for program branches which are two-cycles
All OTP area GOTO instruction
All OTP area subroutine CALL instruction
8-bit wide data path
8-level deep hardware stack
2K x 16 bits on chip OTP
36x8 bits on chip special purpose registers and 96 x 8 bits on chip general purpose registers (SRAM)
Operating speed: DC-20 MHz clock input, or DC-100 ns instruction cycle
Direct, indirect addressing modes for data accessing
Three real time down-count Timer/Counter with 3-bit programmable prescaler
- TMR1: 8-bit, PWM1 & Timer

- TMR3: 8-bit, Timer
Software controlled 4-COM lines LCD driver with 1/2bias
Built-in 3 levels Low Voltage Detector (LVDT) (2.2V/2.6V/3.7V) for Brown-out Reset (BOR)
Power-up Reset Timer (PWRT)
On chip Watchdog Timer (WDT) with internal oscillator for reliable operation and soft-ware watch-dog
enable/disable control
Three I/O ports Port A, Port B and Port C with independent direction control
- 21 Bi-direction I/O port (Programmable Pull-up enable in Input mode)
- One Input only port (IOA7/RSTB)
Four kinds of interrupt source: 3 Timers/Counters, 8 external interrupt sources: IOA0~IOA7, Internal watchdog
timer (i_WDT) wakeup, and A/D end of conversion
Wake-up from SLEEP:
