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.
Uses contents of FSR0 to address data memory - value of FSR0 (not a physical register).
Uses contents of FSR1 to address data memory - value of FSR1 (not a physical register).
Uses contents of FSR2 to address data memory - value of FSR2 (not a physical register).
