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: 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.
