Description
Reserved
These bits are always read as undefined value.
If a port 3 read is performed while P3DDR bits are
set to 1, the P3DR values are read. If a port 3 read
is performed while P3DDR bits are cleared to 0,
the pin states are read.
Reserved
These bits are always read as undefined value.
Output data for a pin is stored when the pin is
specified as a general purpose output port.
