P1MDOUT.[7:0]: Port1 Output Mode Bits.
0: Port Pin output mode is configured as Open-Drain.
1: Port Pin output mode is configured as Push-Pull.
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.
P2.[7:0]: Port2 Output Latch Bits.
(Write - Output appears on I/O pins per XBR0, XBR1, XBR2, and XBR3 Registers)
0: Logic Low Output.
1: Logic High Output (open if corresponding P2MDOUT.n bit = 0).
(Read - Regardless of XBR0, XBR1, XBR2, and XBR3 Register settings).
0: P2.n pin is logic low.
1: P2.n pin is logic high.
P2.[7:0] can be driven by the External Data Memory Interface (as Address[15:8] in Multiplexed
mode, or as Address[7:0] in Non-multiplexed mode). See
ORY INTERFACE AND ON-CHIP XRAM” on page 145
Memory Interface.
P2MDOUT.[7:0]: Port2 Output Mode Bits.
0: Port Pin output mode is configured as Open-Drain.
1: Port Pin output mode is configured as Push-Pull.
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.
