P1DDR is an 8-bit write-only register, the individual bits of which specify input or output for the
pins of port 1. P1DDR cannot be read; if it is, an undefined value will be read.
Setting a P1DDR bit to 1 makes the corresponding port 1 pins output pins, while clearing the bit to
0 makes the pins input pins.
P1DDR is initialized to H'00 by a reset, and in hardware standby mode. It retains its prior state in
software standby mode.
Whether the address output pins maintain their output state or go to the high-impedance state in a
transition to software standby mode is selected by the OPE bit in SBYCR.
