In the "CAN 7 Periodic Software Read Back of Static Configuration Registers", the CAN register is checked.

At that time, I detected that "DCAN TEST - EXL" was unintentionally changing.

What are the conditions under which "EXL" changes?

I don't really understand this question.

Did you run some *code* and during that code run, you saw that the EXL bit (8) of the Test Register in the DCAN was cleared as a side-effect of
some other operation? And you don't know what that operation was?

If so do you have the code that you ran to share?

Thank you.
There was not enough way to find me.
I was able to find the clear code of EXL bit (8).
