Port 7 is an 8-bit I/O port and has the following registers.
• Port 7 data direction register (P7DDR)
• Port 7 data register (P7DR)
• Port 7 register (PORT7)
9.6.1
P7DDR specifies input or output of the port 7 pins using the individual bits. P7DDR 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.

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