8.6
Port 6 is an 8-bit I/O port that also has other functions. The port 6 has the following registers.
• Port 6 data direction register (P6DDR)
• Port 6 data register (P6DR)
• Port 6 register (PORT6)
8.6.1
The individual bits of P6DDR specify input or output for the pins of port 6. P6DDR cannot be
read; if it is, an undefined value will be read.
8.6.2
P6DR stores output data for the port 6 pins.

Description
When a pin function is specified to a general purpose
I/O, setting this bit to 1 makes the corresponding port 6
pin an output pin, while clearing this bit to 0 makes the
pin an input pin.
Description
Output data for a pin is stored when the pin function is
specified to a general purpose output.
