Solution

The Capture/Compare/PWM (CCP) module of PIC microcontroller in compare mode, in addition to Timer 1, primarily serves the function of comparing the value of the Timer 1 with a predefined value.

Here are the steps:

  1. The user sets a predefined value in the CCP register.
  2. The CCP module starts comparing the value of Timer 1 with the value in the CCP register.
  3. When the value of Timer 1 matches the value in the CCP register, the CCP module can trigger an interrupt.
  4. This interrupt can be used to perform various tasks such as changing the state of an output pin, triggering an ADC conversion, or signaling to the CPU that a certain time period has elapsed.

So, in compare mode, the CCP module essentially acts as a programmable interrupt generator that can trigger an interrupt at a specific time.
