Valid when CCP2MX is set in all devices and in all operating modes (default). RE7 is the alternate assignment
for ECCP2/P2A for all PIC18F6525/6621 devices and PIC18F8525/8621 devices in Microcontroller modes
when CCP2MX is not set; RB3 is the alternate assignment for PIC18F8525/8621 devices in all other operating
modes.
