Write - Output appears on I/O pins per XBR0, XBR1, and XBR2 Registers
0: Logic Low Output.
1: Logic High Output (open-drain if corresponding P0MDOUT.n bit = 0)
Read - Always reads ‘1’ if selected as analog input in register P0MDIN. Directly reads Port
pin when configured as digital input.
0: P0.n pin is logic low.
1: P0.n pin is logic high.
Port pins configured as analog inputs have their weak pull-up, digital driver, and digital
receiver disabled.
0: Corresponding P0.n pin is configured as an analog input.
1: Corresponding P0.n pin is configured as a digital input.
