Write - Output appears on I/O pins.
0: Logic Low Output.
1: Logic High Output (Open-Drain if corresponding P6MDOUT bit = 0). See SFR Definition
18.18.
Read - Returns states of I/O pins.
0: P6.n pin is logic low.
1: P6.n pin is logic high.
0: Port Pin output mode is configured as Open-Drain.
1: Port Pin output mode is configured as Push-Pull.
P6.[7:0] can be driven by the External Data Memory Interface (as Address[15:8] in Multiplexed
mode, or as Address[7:0] in Non-multiplexed mode). See
