RA6 and associated bits are configured as a port pin in RCIO and ECIO Oscillator modes only and read ‘0’ in all other
oscillator modes.
Bit 21 of the TBLPTRU allows access to the device configuration bits.
These registers are unused on PIC18F6525/6621 devices and read as ‘0’.
RG5 is available only if MCLR function is disabled in configuration.
