Section 11 I/O Ports
11.3
Port 3 is a 6-bit I/O port that also has other functions. Port 3 has the following registers. For the
port function control registers, refer to section 11.18, Port Function Control Registers.
• Port 3 data direction register (P3DDR)
• Port 3 data register (P3DR)
• Port 3 register (PORT3)
• Port 3 open drain control register (P3ODR)
• Port function control register 2 (PFCR2)
11.3.1
The individual bits of P3DDR specify input or output for the pins of port 3. P3DDR cannot be
read; if it is, an undefined value will be read.

Description
Reserved
These bits are always read as 0, and cannot be
modified.
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.
