16-bit Timer Pulse Output Operation
In the timer pulse output function, a pulse signal with an arbitrary frequency can be output from TMnIO pin.
Timers can output the signal with twice the cycle which is set in TMnOC1 or twice the cycle of the 16-bit full
count.
The pulse output pin is shown in Table:9.1.1.
Table:9.5.1 shows register settings that control timer interrupt generation sources and timer pulse output cycles.
