Figure 6.3.3 shows an example of operation in the timer mode.
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.
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
