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
Timer3 is referred to in the figure for clarity.
FIGURE 13-1:

- Exception 1: If PWM duty cycle is 0x0000,
- Exception 2: If duty cycle is greater than PRx,
OCxR
the OCx pin will remain low.
the pin will remain high.
