11. Wakeup Interrupts
The wakeup interrupt function detects wakeup interrupt requests from external devices by detecting “L” levels
input to the wakeup interrupt input pins (WI0 to WI7) and passes these to the CPU for interrupt processing.
Wakeup interrupts can be used to wakeup the microcontroller from standby mode. (However, wakeup interrupts
cannot be used to recover from hardware standby mode.)
Not supported by the extended intelligent I/O service (EI2OS) .
Wakeup interrupt functions
Block diagram
Function and Control
Input pins
8 channels (8 pins : WI0 to WI7)
Interrupt trigger
“L” level inputs. One interrupt flag is shared by all eight channels.
Interrupt control
Interrupt requests can be enabled or disabled in the wakeup interrupt control
register (EICR) .
Interrupt flag
Interrupt requests are stored in the wakeup interrupt flag register (EIFR) .
EI2OS support
Not supported by the extended intelligent I/O service (EI2OS) .
