How do I give a radio control car autonomous control

[Kenjones1935]

To run a Radio Control car from the PIC I need to create two PWM signals. One for the Speed Control that controls the drive wheels and one for the Servo that controls the steering. I see that I am to use CCP1 and CCP2 as outputs.

I also need to interpret a PWM signal (on radio channel 3) which tells the PIC to toggle between radio control and autonomous control. The information on this channel is simple. It is binary, but it is still PWM (I believe).

I am under the impression (mistaken I hope) that the PWM interpreter requires that CCP1 be an input. PLease see "Enhanced Capture/Compare/PWM(CCP1) chapter 11.1, page124 of DS41291D.

Do I have another choice for a pin to connect to channel 3 of the radio receiver?
