Legend:
x
= unknown, u = unchanged, – = unimplemented, q = value depends on condition
Note 1:
RA6 and associated bits are configured as port pins in RCIO and ECIO Oscillator modes only and read ‘0’ in all other oscillator
modes.
2:
Bit 21 of the TBLPTRU allows access to the device configuration bits.
3:
These registers are unused on PIC18F6X20 devices; always maintain these clear.
