10.5
Port 5 is a 4-bit I/O port. The port 5 has the following registers.
• Port 5 data direction register (P5DDR)
• Port 5 data register (P5DR)
• Port 5 register (PORT5)
10.5.1
The individual bits of P5DDR specify input or output for the pins of port 5.
P5DDR 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 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.
Output data for a pin is stored when the pin function
is specified to a general purpose I/O.
