     ● SLOW Mode: CPU running at Slow-clock

     ● IDLE Mode: Fast-clock and CPU stop; Slow-clock keep running.

     ● STOP Mode: All clocks and CPU stop.

7.   Two Independent Timers

     ● Timer0

       - 8-bit timer divided by 1~256 pre-scale option / auto-reload / counter / interrupt / stop function

     ● Timer1

       - 8-bit timer divided by 1~256 pre-scale option / auto-reload / interrupt / stop function

8.   Interrupt

      ● Three External Interrupt pins

         - 1 pin is falling edge wake-up triggered & interrupts

         - 2 pins are rising or falling edge wake-up triggered & interrupt

     ● Timer0 / Timer1 / Wake-up Timer Interrupt

     ● PWM Interrupt

     ● LVD interrupt

9.   Wake.up Timer (WKT)

     ● Clocked by built-in RC oscillator with 4 adjustable interrupt times

        - 12 ms / 25 ms / 50 ms / 100 ms @ 4V

10. Watchdog Timer (WDT)

     ● Clocked by built-in RC oscillator with 4 adjustable reset times

       - 100 ms / 200 ms / 800 ms / 1600 ms @ 4V

     ● Watchdog timer can be disabled / enabled in STOP mode

11. Five 16-bit PWMs (shared periods)

     ● PWM0, PWM1, PWM2, PWM4, PWM5

       - 16 bits, individual duty-adjustable, shared period-adjustable controlled PWM

       - PWM clock source: System clock (Fsys), FIRC (16 MHz) or FIRC*2 (32MHz)

12. Reset Sources

     ● Power on Reset
