Section 10 I/O Ports
10.4
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)
10.4.1
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. This register is a write-only register, and cannot be
written by bit manipulation instruction. For details, see section 2.9.4, Access Methods 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.
