8.1
Port 1 is an 8-bit I/O port that also has other functions. The port 1 has the following registers.
• Port 1 data direction register (P1DDR)
• Port 1 data register (P1DR)
• Port 1 register (PORT1)
8.1.1
The individual bits of P1DDR specify input or output for the pins of port 1. P1DDR cannot be
read; if it is, an undefined value will be read.

Description
When a pin function is specified to a general purpose
I/O, setting this bit to 1 makes the corresponding port 1
pin an output pin, while clearing this bit to 0 makes the
pin an input pin.
