P0MDOUT.[7:0]: Port0 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.
P1.[7:0]: Port1 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 P1MDOUT.n bit = 0).
(Read - Regardless of XBR0, XBR1, XBR2, and XBR3 Register settings).
0: P1.n pin is logic low.
1: P1.n pin is logic high.
P1.[7:0] can be configured as inputs to ADC1 as AIN1.[7:0], in which case they are ‘skipped’
by the Crossbar assignment process and their digital input paths are disabled, depending on
P1MDIN (See SFR Definition 17.8). Note that in analog mode, the output mode of the pin is
determined by the Port 1 latch and P1MDOUT (SFR Definition 17.9). See
ADC (ADC2, C8051F040/1/2/3 Only)” on page 91
P1.[7:0] can be driven by the External Data Memory Interface (as Address[15:8] in Non-mul-
tiplexed mode). See
