Section 10 I/O Ports
10.2
Port 2 is an 8-bit I/O port that also has other functions. The port 2 has the following registers.
• Port 2 data direction register (P2DDR)
• Port 2 data register (P2DR)
• Port 2 register (PORT2)
10.2.1
The individual bits of P2DDR specify input or output for the pins of port 2.
P2DDR cannot be read; if it is, an undefined value will be read.

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.
