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

PWM Frequency = 1/[PWM Period]
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.

The PWM duty cycle is specified by writing to the
OCxRS and OCxR registers. The OCxRS and OCxR
registers can be written to at any time, but the duty
cycle value is not latched until a match between PRy
and TMRy occurs (i.e., the period is complete). This
provides a double buffer for the PWM duty cycle and is
essential for glitchless PWM operation.
Some important boundary parameters of the PWM duty
cycle include:
• If OCxR, OCxRS, and PRy are all loaded with
• ·If OCxRS is greater than PRy, the pin will remain
See Example 14-1 for PWM mode timing details.

frequencies and resolutions for a device operating at
4 MIPS and 10 MIPS, respectively.
