P5.[7:0]: Port5 Output Latch Bits.
Write - Output appears on I/O pins.
0: Logic Low Output.
1: Logic High Output (Open-Drain if corresponding P5MDOUT bit = 0). See SFR Definition
17.19.
Read - Returns states of I/O pins.
0: P5.n pin is logic low.
1: P5.n pin is logic high.
P5.[7:0] can be driven by the External Data Memory Interface (as Address[15:8] in Non-mul-
tiplexed mode). See
