19.1
The 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.
Table 19-1 shows the timer resources required by the
CCP module.
