9.2
Port 2 is an 8-bit I/O port and has the following registers.
• Port 2 data direction register (P2DDR)
• Port 2 data register (P2DR)
• Port 2 register (PORT2)
9.2.1
P2DDR specifies input or output of the port 2 pins using the individual bits. P2DDR cannot be
read; if it is, the read value is undefined. Since this register is a write-only register, bit-
manipulation instructions should not be used when writing. See section 2.9.4, Access Method for
Registers with Write-only Bits.

Description
When a pin is specified as a general purpose I/O
port, setting this bit to 1 makes the corresponding
port 2 pin an output pin. Clearing this bit to 0 makes
the pin an input pin.
