32.1.2.5.1 Pulsed Compare Mode

In Pulsed Compare mode, the duty cycle is one prescaled PWM clock period that starts when the timer matches the parameter value and ends one prescaled PWM clock period later. The outputs start in the Inactive state and then go Active during the duty cycle. Block and timing diagrams follow.
