i'm not a 3.1 user but from all i have seen those defines only refer to the hpwm command

i don't have access to the PBP3_PPS_notes.txt notes file either, so does it reference to ccp capture mode at all ?

i would set porta.0 to digital and input mode and ccp1pps to use ra.0 manually [by default ccp1pps i/p is ra.5]
