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.
