9.5
Port 5 is a 3-bit I/O port and has the following registers.
• Port 5 data direction register (P5DDR)
• Port 5 data register (P5DR)
• Port 5 register (PORT5)
9.5.1
P5DDR specifies input or output of the port 5 pins using the individual bits. P5DDR 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.
9.5.2
P5DR stores output data for port 5 pins.

Description
Reserved
These bits are always read as undefined value and
cannot be modified.
When a pin is specified as a general purpose I/O
port, setting this bit to 1 makes the corresponding
port 5 pin an output pin. Clearing this bit to 0 makes
the pin an input pin.
Description
Reserved
These bits are always read as undefined value and
cannot be modified.
Output data for a pin is stored when the pin is
specified as a general purpose output port.
