Note:
Port 1 Data Direction Register (P1DDR)
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 returned.
P1DDR is initialized to H'00 by a reset and in hardware standby mode. It retains its prior state in
software standby mode. The address output pins maintain their output state in a transition to
software standby mode.

Read/Write
Mode 1
The corresponding port 1 pins are address outputs, regardless of the P1DDR setting.
In hardware standby mode, the address outputs go to the high-impedance state.
Modes 2 and 3 (EXPE = 1)
The corresponding port 1 pins are address outputs or PWM outputs when P1DDR bits are set
to 1, and input ports when cleared to 0.
Modes 2 and 3 (EXPE = 0)
The corresponding port 1 pins are output ports or PWM outputs when P1DDR bits are set to 1,
and input ports when cleared to 0.
