Wake up from VLLS3  by NMI in K82

Hi !

I'm using power manager example for K82 and wakeup ( via reboot ) from VLLS3  low power mode work properly by using GPIO pin.

 

NMI pin is also can be used for wake up , if it configured as NMI by using Config Tool.

 

I can see NMI wake up MCU but execution flow is not go in similar way as some pin configured for useing LLWU controller.

 

How to organize clean up flow in NMI interrupt handler in case usage of it for wakeup MCU from VLLSx modes ?

 

Also if I press NMI button on FRDM-K82 evaluation board, I can see at list 10-15 calls of NMI handler.

How-to supress "button drizzling" on this pin ? What can be configured for this pin ?

SW3 button is able to react on rising or falling edge but NMI always generate a lot of noise.

Regards,

Eugene
