8.2
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)
8.2.1
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.
8.2.2
P2DR stores output data for the port 2 pins.

Description
When a pin function is specified to a general purpose
I/O, setting this bit to 1 makes the corresponding port 2
pin an output pin, while clearing this bit to 0 makes the
pin an input pin.
Description
Output data for a pin is stored when the pin function is
specified to a general purpose output.
