ECCP2/P2A are multiplexed with RC1 when CCP2MX is set; with RE7 when CCP2MX is cleared and the device is configured in
Microcontroller mode; or with RB3 when CCP2MX is cleared in all other program memory modes.
P1B/P1C/P3B/P3C are multiplexed with RE6:RE3 when ECCPMX is set and with RH7:RH4 when ECCPMX is not set.
RG5 is multiplexed with MCLR and is only available when the MCLR Resets are disabled.
External memory interface pins are multiplexed with PORTD (AD7:AD0), PORTE (AD15:AD8) and PORTH (A19:A16).
