Description
If a port 2 read is performed while P2DDR bits are
set to 1, the P2DR values are read directly,
regardless of the actual pin states. If a port 2 read
is performed while P2DDR bits are cleared to 0, the
pin states are read.
8.3.3 Port 2 Pull-Up MOS Control Register (P2PCR)
P2PCR controls the port 2 on-chip input pull-up MOSs.
