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.
Description
The input pull-up MOS is turned on when a P2PCR bit
is set to 1 in the input port state.
