RA6 and associated bits are configured as port pins in RCIO, ECIO and INTIO2 (with port function on RA6) Oscillator mode 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.
If PBADEN = 0, PORTB<4:0> are configured as digital input and read unknown, and if PBADEN = 1, PORTB<4:0> are configured as
analog input and read ‘0’ following a Reset.
These registers and/or bits are not implemented on the PIC18F2X31 devices, and read as ‘0’.
The RE3 port bit is only available when MCLRE fuse (CONFIG3H<7>) is programmed to ‘0’. Otherwise, RE3 reads ‘0’. This bit is read-only.
