high current in System off

ToTo

I don't understand why i have a current consumption of 0.535mA in system off. In my soft i use PWM, SPI a Button,, I put all things off before i go to system off but still not understanding why is high.. Any one have had such a problem with a consumption around to what i find ?

    Hi,

    Are you debugging when doing the measurements? In debug mode system off does not work. Instead, emulated system off is used which does not go to deep sleep and the CPU continues to run. System OFF will be emulated to secure that all required resources needed for debugging are available during System OFF. If you are not in debug mode, another theory could be that a GPIO interrupt is waking up the chip immediately after you enter SystemOff.
