14.3.1
The PWM period is specified by writing to PRy, the
Timer Period register. The PWM period can be
calculated using Equation 14-1.

Note 1: The OCx outputs must be assigned to an available RPn pin before use. See Section 10.4 “Peripheral Pin
Note 1:
2: The OCFA/OCFB fault inputs must be assigned to an available RPn/RPIn pin before use. See Section 10.4
PWM PERIOD
A PRy value of N will produce a PWM period of N + 1 time base count cycles. For example, a value of 7
written into the PRy register will yield a period consisting of 8 time base cycles.
