These bits are unimplemented on PIC18F2XK20 devices; always maintain these bits clear.
PORTA<7:6> and their direction bits are individually configured as port pins based on various primary
oscillator modes. When disabled, these bits read as ‘0’.
RE3 port bit is available only as an input pin when the MCLRE Configuration bit is ‘0’.
These registers are not implemented on PIC18F2XK20 devices.
