11.2
Port 2 is an 8-bit I/O port that also has other functions. Port 2 has the following registers. For the
port function control registers, refer to section 11.18, Port Function Control Registers.
• Port 2 data direction register (P2DDR)
• Port 2 data register (P2DR)
• Port 2 register (PORT2)
• Port 2 open drain control register (P2ODR)
• Port function control register 3 (PFCR3)
11.2.1
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.

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