As I told above, a single CCP will work only in one mode at a time. I think you should do like this.

  • You can use a normal input interrupt or on-change interrupt to detect rise and fall.
  • Start a timer when rise is detected and stop it when fall happens.
  • So you will get the time period from the timer count.
  • Use that CCP module only in PWM mode.
  • Just change the duty cycle based on the timer value.
