Section 9 I/O Ports
9.4.1
P7DDR specifies input or output of the port 7 pins using the individual bits. P7DDR cannot be
read; if it is, an undefined value will be read.
The value of this register when read is undefined after a bit manipulation instruction is executed.
To prevent undefined read values, do not use bit manipulation instructions to write to this register.
For details, see section 2.9.4, Access Methods for Registers with Write-Only Bits.
9.4.2
P7DR stores output data for port 7 pins.

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.
Description
Output data for a pin is stored when the pin is specified
as a general purpose output port.
