I am using Sama4s and i want to use the external interrupt on dat1 line.
I can not enable it and write the ISR which will be related to this interrupt.
Thanks alot

Hi ahmed

For such a general query I suggest that you look at the ASF ISR examples (eg. LOW_POWER uses the RTC and a button interrupt I think) for whatever dev board you have at hand. Or just pick any one for a sam4s dev board and read through it to get a start on your user board implementation.

Go well.
