Bit 7:

UNUSED. Read = 0b. Write = don’t care.

Bits 6–0: P4.[6:0]

Write - Output appears on I/O pins per Crossbar Registers.

0: Logic Low Output.

1: Logic High Output (high impedance if corresponding P4MDOUT.n bit = 0).

Read - Directly reads Port pin.

0: P4.n pin is logic low.

1: P4.n pin is logic high.
