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.
