(7) Timer

- Timer 0

16-bit timer/counter

2-bit prescaler + 8-bit programmable prescaler

Mode 0 : Two 8-bit timers with programmable prescaler

Mode 1 : 8-bit timer with programmable prescaler + 8-bit counter

Mode 2 : 16-bit timer with programmable prescaler

Mode 3 : 16-bit counter

The resolution of Timer is tCYC. (tCYC: cycle time)

- Timer 1

16-bit timer/PWM

Mode 0 : Two 8-bit timers

Mode 1 : 8-bit timer + 8-bit PWM
