Description
An output data for a pin is stored when the pin function
is specified to a general purpose output port.
Description
If this register read is performed while P1DDR bits are
set to 1, the P1DR values are read. If this register read
is performed while P1DDR bits are cleared to 0, the pin
states are read.
