STCU2 BIST with FCCU question

[Pusoy]

Hi,

"In the section of STCU2 in the S32K3XX reference manual, there is a description about the FCCU interface.
1. I cannot find 'the description of FCCU fault injection mechanism'. Can you please point out where it is?
Thank you very much!"

Hello,

Well that is very simple.

FCCU NCFF

So in other words, FCCU can inject the fault only to result register STCU ERR, so you can test the reaction path from STCU to FCCU.

Best regards,

Peter
