Hi @Mmmmmm ,
Thank you for your interest in Infineon Semiconductor products and for the opportunity to serve you.
Actually, I'm not clear with your question, can you clarify it again?

Hi @Mmmmmm ,
Thank you for your clarification.
I use the TC397 Tri-Board for testing, and I find the STMEM4 is 0x0000_0001 after the reset event arises.
Just as the figure shows, so I was wondering if you can list the steps you tested.

Hi
Whether you mean the value of STMEM4 is 0x0000_0001, after executing the LIBIST evaluation, it becomes 0x401, is my understanding right?

Yes exactly

Hi @Mmmmmm ，

What IDE and demo code did you use? as I've not replicated the phenomenon when using the Aurix Development Studio and Infineon's AURIX demos.

BR,
