9. TIMER/COUNTER FUNCTION

The timer/counter function has the following features.

16-bit timer/counter (TM0, TM1)

• Capture/compare common registers: 2 for each

• Interrupt request sources

• Capture/match interrupt requests: 2 sources for each

• Overflow interrupt requests: 1 source for each

• Timer/counter count clock sources: 2 types

(Selection of external pulse input or internal system clock division)

• Either free-running mode or overflow stop mode can be selected as the operation mode when the

timer/counter overflows

• Timer/counter can be cleared by a match of the timer/counter and a compare register

• External pulse outputs: 1 for each

8-bit timers (TM2 to TM5)

• Stand-alone mode (mode in which a single timer is used)

• Interval timer

• External event counter

• Square-wave output

• PWM output

• Cascade connection mode (mode in which two timers are used connected in cascade: 16-bit resolution)

• 16-bit resolution interval timer

• 16-bit resolution external event counter

• 16-bit resolution square-wave output
