x = unknown, u = unchanged, - = unimplemented, q = value depends on condition. Shaded cells are unimplemented.
RA6 and associated bits are configured as port pins in RCIO, ECIO and INTIO2 (with port function on RA6) Oscillator modes only and read
‘0’ in all other oscillator modes.
RA7 and associated bits are configured as port pins in INTIO2 Oscillator mode only and read ‘0’ in all other modes.
Bit 21 of the PC is only available in Test mode and Serial Programming modes.
These registers and/or bits are not implemented on the PIC18F2331/2431 devices and read as ‘0’.
The RE3 port bit is only available for PIC18F4331/4431 devices when the MCLRE fuse (CONFIG3H<7>) is programmed to ‘0’; otherwise, RE3
reads ‘0’. This bit is read-only.
