Do I need to do something more to handle the procedure when the interruption occur ? Do you fellows have any other simple way to handle interruptions ? Thanks very much for your help....

 Thanks for your advice and sorry for incomplete information.

 I'm using an AVR ATMega 2560. I'm not using the avr-ada lib. The way I'm doing the interruptions is just like the link you sent. The interruption is ok, the used vector is in accordance with the enabled interrupt, as I saw in my debug. The problem is: the handled procedure is not called when the interruption ocur.

As I tried to summarize, this is my question...
