PWMs, Timers and Counters
PWMs, Timers and Counters share many capabilities but
each provides specific capabilities.
When to Use a PWM
The most common use of the PWM is to generate periodic waveforms with adjustable duty cycles. The PWM also provides optimized features for power control, motor control, switching regulators and lighting control. The PWM can also be used as a clock divider by driving a clock into the clock input and using the terminal count or a PWM output as the divided clock output.
