NMI External Interrupt in Arduino Due

Projects Programming
1

Hi Team,

Arduino Due uses SAM3X8E processor.

I cannot see any specific pin for NMI (non maskable interrupt).
External interrupt is configurable on any of the input pin.

In datasheet they have mentioned regarding NMI interrupt but I am not getting how to configure the same.

In interrupt vector table the vector address location for NMI is showing "Reserved".

So the confusion is that is there anything like non maskable interrupt in (Arduino Due which uses SAM3X8E).

Can NMI like function be achieved using interrupt on GPIO? How?

Is there any difference between a Non Maskable Interrupt and an external interrupt that you always handle ?

Thanks!!

Nope.. No difference as such but I was confused just because the way they have mentioned in the datasheet.
