Dieter, maybe we could have a debug-version of moko11 to implement a service AT command to tweak those config registers. This way we could ask users who actually can reproduce #1024 to check if there's any difference when issuing this power tweaking back and forth. > > Is there anything else that's driven by the 32768 Hz clock that > we can access, e.g., a RTC or some counter ?
