The output compare module can select either Timer2
or Timer3 for its time base. The module compares the
value of the timer with the value of one or two Compare
registers depending on the operating mode selected.

The state of the output pin changes when the timer
value matches the Compare register value. The output
compare module generates either a single output
pulse, or a sequence of output pulses, by changing the
state of the output pin on the compare match events.
The output compare module can also generate
interrupts on compare match events.
The output compare module has multiple operating
modes:
• Active-Low One-Shot mode
• Active-High One-Shot mode
• Toggle mode
• Delayed One-Shot mode
• Continuous Pulse mode
• PWM mode without Fault Protection
• PWM mode with Fault Protection
