8.4 Timers/Counters
Three timer/counter units and one timer unit are incorporated.
Moreover, seven interrupt requests are supported, allowing these units to function as seven timer/counter units.
Table 8-2. Timer/Counter Operation
Note
The one-shot pulse output function makes the level of a pulse output active by software, and makes the
level of a pulse output inactive by hardware (interrupt request signal).
Note that this function differs from the one-shot timer function of timer/counter 2.
