‧ 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
