Hi @JasonQ
The most common faults on the kinetis devices are:
-Caused by a peripheral when you try to use it without turning on the clock.
-Trying to write on a read only location.
-Accessing or reading blank flash locations.
The Faults are generated with the NVIC, since the faults are from the Cortex Architecture, you can find more information on different websites from our own, for example this link. Also, this community post could provide you more information.
Let me know if you have another question.
Best Regards, Miguel.
