33.4 Operation with Timer1 Gate

The output resulting from a comparator operation can be used as a source for gate control of the odd numbered timers (Timer1, Timer3, etc.). See Timer1 Gate for more information. This feature is useful for timing the duration or interval of an analog event.

It is recommended that the comparator output be synchronized to the timer by setting the SYNC bit in the CMxCON0 register. This ensures that the timer does not increment while a change in the comparator is occurring. However, synchronization is only possible with the Timer1 clock source. Synchronization with the other odd numbered timers is only possible when they use the same clock source as Timer1.
