How to wake up SAMR34 microcontroller from standby mode via the GPIO event (sleepwalking)

Hello,
I am looking for a solution to wake up SAMR34 microcontroller from SLEEP_MODE_STANDBY via the GPIO event (I do not want to reset the device). Does anyone have any examples? The majority of examples is based on a microcontroller reset (sleep in SLEEP_MODE_BACKUP)

    I solved the problem, everything is in the ASF examples:

    Please look into the SAMR34 Radio Utility Project from Microchip in their SAMR34 Reference Design Package
    https://www.microchip.com/wwwproducts/en/ATSAMR34J18
    In that project, they have implemented sleep modes. With Button interrupt the device will wakeup without resetting the device. You can obtain up to ~1.6uA low power with this code.
