Description
If a port 1 read is performed while the P1DDR bits
are set to 1, the P1DR values are read. If a port 1
read is performed while the P1DDR 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 P1PCR bit
is set to 1.
