8.8
Port 8 is an 8-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)
8.8.1
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.
8.8.2
P8DR stores output data for the port 8 pins.

When a pin function is specified to a general purpose
I/O, setting this bit to 1 makes the corresponding port 8
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 output.
