Watchdog in Software Standby Mode (Sleep)

Hello everyone, I'm wondering if any of you have information on wether or not we can keep the watchdog running while in the Software Standby Mode.

I'm not too sure but I think the OFS0 register is the one where you can change the bit30 to make the Watchdog keep running while sleeping but apparently the OFS0 register is in the flash memory so you can't modify it using code?

I tried modifying the "dfu_minima.hex" file without any luck. I also tried editing the "WDT.cpp" and change the Stop.Control to disable without luck either.

Does anyone have any info?
