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
In modes 2 and 3, the input pull-up MOS is turned
on when a P2PCR bit is set to 1 in the input port
state.
