Fig. 6.4.3 Example of operation in event counter mode
6.4.2 Operation in event counter mode
Figure 6.4.3 shows an example of operation in the event counter mode.
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.
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.
When the counter underflows, the reload register’s contents are reloaded and counting continues.
The timer Bi interrupt request bit is set to “1” when the counter underflows in
