Bits7-0:
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.
Notes:
1.
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
Figure 17.13). Note that in analog mode, the output mode of the pin is determined by the Port 1 latch
and P1MDOUT (Figure 17.14). See
tion about ADC1.
2.
P1.[7:0] can be driven by the External Data Memory Interface (as Address[15:8] in Non-multiplexed
mode). See
Section “16. EXTERNAL DATA MEMORY INTERFACE AND ON-CHIP XRAM”
on page 145
for more information about the External Memory Interface.

Bits7-0:
P1MDIN.[7:0]: Port 1 Input Mode Bits.
0: Port Pin is configured in Analog Input mode. The digital input path is disabled (a read from the
Port bit will always return ‘0’). The weak pull-up on the pin is disabled.
1: Port Pin is configured in Digital Input mode. A read from the Port bit will return the logic level at
the Pin. The state of the weak pull-up is determined by the WEAKPUD bit (XBR2.7, see
Figure 17.9).
