P4.[7:5]: Port4 Output Latch Bits.
Write - Output appears on I/O pins.
0: Logic Low Output.
1: Logic High Output (open, if corresponding P4MDOUT.n bit = 0). See Figure 18.20.
Read - Returns states of I/O pins.
0: P4.n pin is logic low.
1: P4.n pin is logic high.
Note: P4.7 (/WR), P4.6 (/RD), and P4.5 (ALE) can be driven by the External Data Memory
Interface. See
