Port 8 is a 6-bit I/O port that also has other functions. The port 8 has the following registers.
• Port 8 data direction register (P8DDR)
• Port 8 data register (P8DR)
• Port 8 register (PORT8)
10.7.1
The individual bits of P8DDR specify input or output for the pins of port 8.
P8DDR 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.
