4.2.6 Port 7
using port mode register 7 (PM7). When the P70 to P76 pins are 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).
Port 7 is a 7-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.
Reset signal generation sets port 7 to input mode.
Figure 4-13 shows a block diagram of port 7.
