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].

PWM period = [(PRx) + 1] • 4 • T

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
