PWM Period

The PWM period is specified by the TxPR register The PWM period can be calculated using the formula of PWM Period. It is required to have FOSC/4 as the selected clock input to the timer for correct PWM operation.

Note: TOSC = 1/FOSC

When T2TMR is equal to T2PR, the following three events occur on the next increment cycle:

Important: The Timer2 postscaler has no effect on the PWM operation.
