22.1 Function
to KR7) by setting the KRM register.
822
A key interrupt request signal (INTKR) can be generated by inputting a falling edge to the eight key input pins (KR0
Caution If any of the KR0 to KR7 pins is at low level, the INTKR signal is not generated even if a falling
edge is input to another pin.
