Hello Support,

In the Aurix 2G Safety Manual, in the appendix, following section/table
"TC39B - COLD POWER-ON RESET AFTER LBIST EXECUTION"

There I see ECCD and FAULLSTS MTU Register contents for initialized RAM.
By default, those registers are not accessible after LBIST Execution because of MTU is not enabled.
So, how do I verify those MTU register contents?
I am assuming when I enable the MTU in the code, it will clear all those registers.
Hence this question.
Best Regards

Hello,

To read the content of FAULTSTS you need to enable the MTU_CLC, which doesn't clear the any memory and just enables the MTU.
Memory clear happens only when you enable it for test via MEMTEST
