Can CMU be configured in S32? How to write CMU driver? Is there sample code?

Can you tell me which device are you using?

CMU is available in only S32K11x series of devices. Other products in the S32K14x series do not have CMU.

BR!

I am using the S32K118 ，Then I don't know how to configure the CMU, how to verify that the configuration is correct.

Try to manipulate the thresholds in HTCR and LTCR registers,then generate a Loss of Clock reset when monitoring the FIRC.

Thank you for the example you provided last time. How is the CMU1 threshold calculation formula derived? No related formula found on the document
