Hello,

Currently using the LBPORST bit we can identify, if PORST interrupted an ongoing LBIST. Let's consider a case wherein after the successful completion of LBIST, if there is a PORST which erases the LBIST results. Is there a way to identify this case?

Recently,  on my TC397X based controller board,  the LBPORST error was detected by Functional-Safety software occasionally.

Is anyone here can give me some advice on figuring out this issue?
