Appendix B :
1 = Input (Default) / 0 = Output
1 = Input (Default) / 0 = Output
1 = Input (Default) / 0 = Output
If ENAUX bit (IOCFG.3) is set, “MOVX A, @Ri” and “MOVX @Ri, A”
instructions refer to AUXAD instead of P2 register for high address.

-
Quasi-bidirectional port with internal pull-up resistors.
When alternative function is enabled, P4.X must be “1”.
When ADC is used, the pull-up resistors for enabled channel are
automatically disabled.
1 = Pull-up resistor ON (Default) / 0 = Pull-up resistor OFF
1 = Pull-up resistor ON (Default) / 0 = Pull-up resistor OFF
