0: Port Pin output mode is configured as Open-Drain.
1: Port Pin output mode is configured as Push-Pull.
(Write - Output appears on I/O pins per XBR0, XBR1, and XBR2 Registers)
0: Logic Low Output.
1: Logic High Output (open if corresponding P3MDOUT.n bit = 0).
(Read - Regardless of XBR0, XBR1, and XBR2 Register settings).
0: P3.n pin is logic low.
1: P3.n pin is logic high.
SDA, SCL, and RX0 (when UART0 is in Mode 0) and RX1 (when UART1 is in Mode 0) are
always configured as Open-Drain when they appear on Port pins.
P3.[7:0] can be driven by the External Data Memory Interface (as AD[7:0] in Multiplexed
mode, or as D[7:0] in Non-multiplexed mode). See
