‧ 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)

‧ 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 PORTA, PORTB, PORTC and PORTD with independent direction control.
‧ Two output only ports POTRE and PORTF.
‧ 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
    - Green mode : CPU operate on low frequency sub-oscillator
    - Idle mode : CPU idle, LCD display remains working
    - Sleep mode : whole chip stop working
‧ Dual clock Operation: main-oscillator and sub-oscillator
