Description
Reserved
These bits are always read as 0 and cannot be
modified.
Output data for a pin is stored when the pin function
is specified to a general purpose I/O.
If a port 3 read is performed while P3DDR bits are
set to 1, the P3DR values are read. If a port 1 read
is performed while P3DDR bits are cleared to 0, the
pin states are read.
