Note 1: These registers or register bits are not implemented on the PIC18F248 and PIC18F258 and read as ‘0’s.
2: Bit 21 of the TBLPTRU allows access to the device configuration bits.
3: RA6 and associated bits are configured as port pins in RCIO and ECIO Oscillator mode only and read ‘0’ in all other oscillator modes.
