bit 7 bit 0
bit 7-3 Unimplemented: Read as '0'
bit 2-0 PCFG2:PCFG0: A/D Port Configuration Control bits
Note 1: RE0, RE1 and RE2 are implemented on the PIC16C74B only.
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ’1’ = Bit is set ’0’ = Bit is cleared x = Bit is unknown
