4.2.8 Port 7
using port mode register 7 (PM7). When used as an input port, use of an on-chip pull-up resistor can be specified in
1-bit units by pull-up resistor option register 7 (PU7).
input.

Port 7 is an 8-bit I/O port with an output latch. Port 7 can be set to the input mode or output mode in 1-bit units
This port can also be used for key return input, external expansion output (address bus), and interrupt request
Reset signal generation sets port 7 to input mode.
Figure 4-30 shows a block diagram of port 7.
