Patch Set 6: Code-Review-1

Patchset:

PS6: don't reset in the handler, either let it get stuck as before + let the WDT reset it or manually force a immediate wdt reset, because that is a different reset cause than a nvic reset which looks like any other system self reset so it can't be distinguished at the next boot.
