Dear community members,
I have a question according to "OSC_ULP Oscillator Watchdog (ULPWDG)" in chapter 126.96.36.199 in Reference Manual V3.6 of XMC4500 family.
I see that "In case of external crystal failure the clock source switches automatically to the Internal
Slow Clock Source generating f_OSI.".
I just want to ask you whether there is a possibility to check if the internal slow clock source is in use instead of the external crystal. I assumed the SCU.HDCR.RCS bit changes automatically on failure of external crystal but it does not. Is there maybe any bit I can read out for that purpose?
