PWM Period

The PWM period is specified by the T2PR register of Timer2. The PWM period can be calculated using the formula in the equation below.

where T_OSC = 1/F_OSC

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

• T2TMR is cleared
• The CCPx pin is set. (Exception: If the PWM duty cycle = 0%, the pin will not be set.)
• The PWM duty cycle is transferred from the CCPRx register into a 10-bit buffer.
