P1DDR is initialized to H'FF in modes 1 to 4 and H'00 in modes 5 to 7 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. While port 1 acts as an
output port, the value of this register is output. 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.
P1DR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode it
retains its previous setting.
