P1DDR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode
it retains its previous setting. If a P1DDR bit is set to 1, the corresponding pin maintains its output
state in software standby mode.
Port 1 Data Register (P1DR)
P1DR is an 8-bit readable/writable register that stores port 1 output data. When this register is
read, the pin logic level of a pin is read for bits for which the P1DDR setting is 0, and the P1DR
value is read for bits for which the P1DDR setting is 1.
