Operation stops.
Release signal
Reset signal
Interrupt request signal sent from
interrupt enabled hardware
System reset signal (key return reset)
generated by KRn falling edge when
KRREN pin = 1.
Reset signal
Interrupt request signal sent from
interrupt enabled hardware
Note
Can operate only when the noise eliminator is not used (IM02 = 1) by bit 2 of the edge detection mode
register (IM0).
