Port 1 Data Direction Register (P1DDR)
Mode 1
Modes 2 and 3
P1DDR controls the input/output direction of each pin in port 1.
Mode 1: The P1DDR values are fixed at 1. Port 1 consists of lower address output pins. P1DDR
values cannot be modified and are always read as 1.
In hardware standby mode, the address bus is in the high-impedance state.
Mode 2: A pin in port 1 is used for address output if the corresponding P1DDR bit is set to 1, and
for general input if this bit is cleared to 0.
Mode 3: A pin in port 1 is used for general output if the corresponding P1DDR bit is set to 1, and
for general input if this bit is cleared to 0.
In modes 2 and 3, P1DDR is a write-only register. Read data is invalid. If read, all bits always read
1. P1DDR is initialized to H'00 by a reset and in hardware standby mode. In software standby
mode it retains its existing values, so if a transition to software standby mode occurs while a
P1DDR bit is set to 1, the corresponding pin remains in the output state.
