Section 8 I/O Ports
8.2
Port 1 is an 8-bit I/O port. Port 1 pins also function as an address bus and PWM output pins. Port 1
functions change according to the operating mode. Port 1 has an on-chip input pull-up MOS
function that can be controlled by software. Port 1 has the following registers.
8.2.1
P1DDR specifies input or output for the pins of port 1 on a bit-by-bit basis.

Description
In mode 1:
Each pin of port 1 is address output regardless of
the set value of P1DDR.
In modes 2 and 3 (EXPE=1):
The corresponding port 1 pins are address output
or PWM output ports when P1DDR bits are set to
1, and input ports when cleared to 0.
In modes 2 and 3 (EXPE=0):
The corresponding port 1 pins are output ports or
PWM outputs when the P1DDR bits are set to 1,
and input ports when cleared to 0.
