7.2
Port 1 is an 8-bit I/O port. Port 1 pins also function as address bus pins, address/data multiplex bus
pins, and PWM output pins. Pin functions change according to the operating mode.
Port 1 has the following registers.
• Port 1 data direction register (P1DDR)
• Port 1 data register (P1DR)
• Port 1 register (PORT1)
• Port 1 pull-up MOS control register (P1PCR)
7.2.1
The individual bits in P1DDR specify input or output for the pins of port 1. The read value is
undefined.

In normal extended mode
The corresponding port 1 pins are address
outputs when P1DDR bits are set to 1, and input
ports when cleared to 0.
In multiplex extended mode (16-bit bus width)
Operation is not affected
In multiplex extended mode (8-bit bus width)
Operates as single-chip mode
In single-chip mode
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.
