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 output data for pins P1
acts as an output port, the value of this register is output. When a bit in P1DDR is set to 1, if port 1
is read the value of the corresponding P1DR bit is returned. When a bit in P1DDR is cleared to 0,
if port 1 is read the corresponding pin level is read.
P1DR is initialized to H'00 by a reset and in hardware standby mode. In software standby mode it
retains its previous setting.
