21. Wake-up interrupt
Wake-up interrupt pins :
Wake-up interrupt sources : “L” level signal input to a wake-up interrupt pin.
Interrupt control :
Interrupt flag :
Interrupt request :
(1) Register configuration of wake-up interrupt
(2) Block diagram of wake-up interrupt
Wake-up Interrupt Flag Register
Wake-up Interrupt Control Register
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.
