8.4 Timers/Counters

Three timer/event counters and one timer are provided.

In addition, because seven interrupt requests are supported, the timer/counters and timer can be used as seven

timer/counters.

Note

The one-shot pulse output function is used to make a pulse output level active by software and inactive by

hardware (interrupt request signal).

This function is different from the one-shot timer function of timer/event counter 2 in nature.
