These pins constitute a 4-bit I/O port that can be set in the input or
output mode in 4-bit units (group I/O).
In the input mode, these pins are CMOS input pins with a pull-up
resistor, and can be used as the key return input lines of a key
matrix. The standby status is released when at least one of these
pins goes low.
In the output mode, they serve as N-ch open-drain output pins and
can be used as the output lines of a key matrix.
