11.0
The Enhanced Capture/Compare/PWM module is a
peripheral which allows the user to time and control
different events. In Capture mode, the peripheral
allows the timing of the duration of an event. The
Compare mode allows the user to trigger an external
event when a predetermined amount of time has
expired. The PWM mode can generate a Pulse-Width
Modulated signal of varying frequency and duty cycle.
