Note:
Port 1 Data Direction Register (P1DDR): P1DDR is an 8-bit write-only register that can select
input or output for each pin in port 1.
Modes 1 to 4 (Expanded Modes with On-Chip ROM Disabled): P1DDR values are fixed at 1.
Port 1 functions as an address bus.
Mode 5 (Expanded Mode with On-Chip ROM Enabled): After a reset, port 1 functions as an
input port. A pin in port 1 becomes an address output pin if the corresponding P1DDR bit is set to
1, and a generic input pin if this bit is cleared to 0.
Mode 7 (Single-Chip Mode): Port 1 functions as an input/output port. A pin in port 1 becomes an
output port if the corresponding P1DDR bit is set to 1, and an input port if this bit is cleared to 0.
