Hi all,
Other than ESR1 port, can you tell me if there are any other NMI (Non Maskable Interrupt) ports that can be used on AURIX? Can NMI be triggered on active high?
Thank you for your help.
Best regards
Bernie

Hi Bernie,
ESR0 might be used as NMI: ESR0 must be pulled up during PORST.
If error signal drives ESR0 low during PORST then AURIX will never boot up.
If the error signal on ESR0 is ensured not to be active low before AURIX powers up, then it is possible for using ESR0 as NMI.
The intended signal for NMI is ESR1. ESR0 is more intended as reset output.
Best regards

What do you mean by error signal which drive ESR0 to be low during POSRT?.
