NRF9160 watchdog enable during System OFF

Hi,

I have a firmware which need to transit to System-OFF under certain conditions. The startup code of the firmware enables the watchdog timer, which can't be disable once started (register are not available anymore according to NRF9160 specifications).

I observed that the watchdog is still resetting the SoC, even after entering System-OFF. Is it expected behaviour? I didn't found on the NRF9160 specifications if entering System-OFF will disable the watchdog, or keep it running.

Thanks,

Louis
