0: Corresponding Port1 pin Digital Input disabled. (For analog use, i.e., ADC or
comparators).
1: Corresponding Port1 pin Digital Input is enabled.
(Write - Output appears on I/O pins per PRT0MX, PRT1MX, and PRT2MX registers)
0: Logic Low Output.
1: Logic High Output (high impedance if corresponding PRT2CF.n bit = 0)
(Read - Regardless of PRT0MX, PRT1MX, and PRT2MX Register settings).
0: P2.n is logic low.
1: P2.n is logic high.
0: Corresponding P2.n Output Mode is Open-Drain.
1: Corresponding P2.n Output Mode is Push-Pull.
