A = Analog input D = Digital I/O
Shaded cells = Additional channels available on the PIC18F8X8X devices
Legend:
R = Readable bit
- n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared x = Bit is unknown
Note: Channels AN15 through AN12 are not available on the 68-pin devices.
