Note

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.
