13.4.2
The PWM period is specified by writing to the PRx
register. The PWM period can be calculated using
Equation
EQUATION 13-1:
PWM frequency is defined as 1/[PWM period].
When the selected TMRx is equal to its respective
Period register, PRx, the following four events occur on
the next increment cycle:
• TMRx is cleared.
• The OCx pin is set.
• The PWM duty cycle is latched from OCxRS into
• The corresponding timer interrupt flag is set.
See

- Exception 1: If PWM duty cycle is 0x0000,
- Exception 2: If duty cycle is greater than PRx,

the OCx pin remains low.
the pin remains high.
