Description
If a port 3 read is performed while P3DDR bits are set
to 1, the P3DR values are read directly, regardless of
the actual pin states. If a port 3 read is performed while
P3DDR bits are cleared to 0, the pin states are read.
Description
The input pull-up MOS is turned on when a P3PCR bit
is set to 1 in the input port state.
The input pull-up MOS function cannot be used when
the host interface is enabled.
