SOLVED - IOC works on B0 but not B5

[Demon]

you need to read and adhere to the PBP3_PPS_notes.txt file in your pbp3 directory

Aren't those DEFINES the exact same thing as:

PinD2   CON %011010                     ' Datasheet table 13-2
CCP3PPS = PinD2                         ' CCP3 Peripheral input selection

PeripheralCCP3  CON %001011             ' Datasheet table 13-3
RD2PPS = PeripheralCCP3                 ' Pin D2 output source selection

RB5PPS = 0                              ' Disable CCP3 on pin B5 (moved to D2)

Or is there an extra step going on in the background?
