cpu can't go to slepp when gpiote event occured?

[Pupil]

The cpu can't goto sleep when gpiote port event occured,after about 1 second later,the cpu then goes to sleep well,

I use the code bellow to enter sleep mode.Is there any thing wrong ,why when the event occured,thc cpu is can't go to sleep as I wanted?I

__WFE;
__WFI;
__WFI;

It seems like when the int pin trigered gpiote,and stay at high or low level,the next 1or 2 seconds before I wake up from the sleep,and goto sleep again,It consumes that current same as the cpu runing

Not sure what you are doing here, but typically you will have an infinite while() or for() loop in you main, e.g.:

int main(void)
{
    // Init
    
    for(;;)
    {
        // Process application code
        
        // Wait for an event.
        __WFE();
        // Clear the internal event register.
        __SEV();
        __WFE();
    }
}
