Note 1:
Alternate assignment for CCP2 when CCP2MX is not selected (all operating modes except
Microcontroller).
2:
Default assignment when CCP2MX is set.
3:
External memory interface functions are only available on PIC18F8X20 devices.
4:
CCP2 is multiplexed with this pin by default when configured in Microcontroller mode. Otherwise, it is
multiplexed with either RB3 or RC1.
5:
PORTH and PORTJ are only available on PIC18F8X20 (80-pin) devices.
6:
AV
DD
must be connected to a positive supply and AV
SS
must be connected to a ground reference for
proper operation of the part in user or ICSP modes. See parameter D001A for details.
