Rev. 1.0

SFR Definition 17.21.

Bits 7–0: P3.[7:0]

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

0: Logic Low Output.

1: Logic High Output (high impedance if corresponding P3MDOUT.n bit = 0).

Read - Always reads ‘0’ if selected as analog input in register P3MDIN. Directly reads Port

pin when configured as digital input.

0: P3.n pin is logic low.

1: P3.n pin is logic high.
