Hi,

I am trying to add clock monitor unit in s32k116 mcu to the software. I initialized clock as FIRC(48MHz). I added RCCR[REF_COUNT]=42, HTCR[LFREF]=36, HTCR[HFREF]=47, GCR[FCE]=1 and activated PCC_CMUX_CFG. But i dont understand how i can control cmu error and how can i set counter for cmu counts?

Generally, you can either re-configure measured clock to value outside of the thresholds or change the thresholds itself. I can't see other option.
