Note:
8.7
Port 7 is an 8-bit I/O port that also has other functions. The port 7 has the following registers.
• Port 7 data direction register (P7DDR)
• Port 7 data register (P7DR)
• Port 7 register (PORT7)
8.7.1
The individual bits of P7DDR specify input or output for the pins of port 7. P7DDR cannot be
read; if it is, an undefined value will be read.

When a pin function is specified to a general purpose
I/O, setting this bit to 1 makes the corresponding port 7
pin an output pin, while clearing this bit to 0 makes the
pin an input pin.
