Description
P2DR stores output data for the port 2 pins that are
used as the general output port.
If a port 2 read is performed while the P2DDR bits
are set to 1, the P2DR values are read. If a port 2
read is performed while the P2DDR bits are
cleared to 0, the pin states are read.
Description
When the pins are in input state, the corresponding
input pull-up MOS is turned on when a P2PCR bit
is set to 1.
