NVIC & NMI

Fri Apr 01, 2016 10:59 am

I wonder if there is good explaining reference on NVIC priority grouping besides SAM4S datasheet.

Besides that, i havent found any reference in how to register a external NMI and from the ASF sources/examples, there is no obvious way to do it.
Any hint?

Thanks!
