21. Wake-up interrupt
The wake-up interrupt circuit detects the signals of the “L” levels input to the external interrupt pins and to
generate interrupt request to the CPU. These interrupts can wake up the CPU from standby mode.
Wake-up interrupt pins :
8 pins (P00/KSI0 to P07/KSI7) .
Wake-up interrupt sources : “L” level signal input to a wake-up interrupt pin.
Enables or disables to input wake-up interrupt controlled by wake-up interrupt control
register (EICR) .
IRQ flag bit of wake-up interrupt flag register (EIFR) . Flag set
when there is an IRQ.
Interrupt request :
Interrupt request #20 is generated if any enabled external interrupt pin goes LOW.
