5.4.2 Operation in event counter mode
Figure 5.4.4 shows an example of operation in the event counter mode.
Timer Ai interrupt
When the count start bit is set to “1,” the counter starts counting of the count source.
The counter counts the count source’s valid edges.
The timer Ai interrupt request bit is set to “1” when the counter underflows or overflows in
When the counter underflows or overflows, the reload register’s contents are reloaded and counting
The interrupt request bit remains set to “1” until the interrupt request is accepted or the interrupt request
bit is cleared to “0” by software.
