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 Multi-
plexed mode, or as Address[7:0] in Non-multiplexed mode). See
Data Memory Interface and On-Chip XRAM” on page 187
External Memory Interface.
P1MDIN.[7:0]: Port 2 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 pullup 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 pullup is determined by the WEAKPUD bit (XBR2.7,
see SFR Definition 17.3).
