Alternate assignment for CCP2/P2A in PIC18F8X2X devices when CCP2MX (CONFIG3H<0>) is not set (all Program
Memory modes except Microcontroller).
Default assignment for CCP2/P2A when CCP2MX is set (all devices).
External memory interface functions are only available on PIC18F8X2X devices.
Default assignment for P1B/P1C/P3B/P3C for PIC18F8X2X devices when ECCPMX (CONFIG3H<1>) is set, and for all
PIC18F6X2X devices.
Alternate assignment for CCP2/P2A in PIC18F8X2X devices when CCP2MX is not set (Microcontroller mode).
PORTH and PORTJ (and their multiplexed functions) are only available on PIC18F8X2X devices.
Alternate assignment for P1B/P1C/P3B/P3C for PIC18F8X2X devices when ECCPMX (CONFIG3H<1>) is not set.
AVDD must be connected to a positive supply and AVSS must be connected to a ground reference for proper operation of
the part in User or ICSP modes. See parameter D001A for details.
