The timer/counter 1 has the following four operating modes:
0
[Hz]
When a match between the counter value and the TREG1A register value is detected,
an INTTMR1 interrupt is generated and the counter is cleared. The counter continues
counting up after it has been cleared.
Source Clock
In the timer mode, the counter counts up on the rising edge of the internal clock.
