2: Bit 21 of the TBLPTRU allows access to the device configuration bits.
3: These registers and bits are reserved on the PIC18F2X2 devices; always maintain these clear.
x = unknown, u = unchanged, - = unimplemented, q = value depends on condition
RA6 and associated bits are configured as port pins in RCIO and ECIO Oscillator mode only and read '0' in all other Oscillator modes.
