Hi,

Thank you so much for your interest in our products and for using our community.

In the S32K3 page there is a training presentation S32K3xx PIT and STM with RTD - Training that explains in detail the configuration and API functions of the STM module. And at the same time an example code is included.

Hope it helps you. Please let me know if you have more questions about it.

Have a nice day!
