Description
P3DR stores output data for the port 3 pins that are
used as the general output port.
If a port 3 read is performed while the P3DDR bits
are set to 1, the P3DR values are read. If a port 3
read is performed while the P3DDR 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 P3PCR bit is
set to 1.
