I'm seeing a low to high pulse of about 80ms on all I/O for my SPC58xx292 on a 57xx mother board when I switch the power on.

I don't see this same pulse when doing a software reset using a debugger. Is there a configuration issue that I am missing or is there some issue with the hardware that is causing this?

Hello Nlamb ,

I am checking with Soc Functional valid team.

Maybe , it is due to the Reset procedure (Reset Generation Module Reset sequence)
