I just want a simple example about how to use the gpio interrupt. My problem is that I can't get the gpio interrupt map in http://www.altera.com/literature/hb/cyclone-v/cv_54006.pdf page6-12.
Does the gpio controller share the interrup number with other peripherails?Link Copied

In case others have the same question, in that document you'll find the generic interrupt controller (GIC) IRQ mapping. Each GPIO has it's own dedicated interrupt line so it's just a matter of making sure the GIC is configured properly to listen for a particular GPIO interrupt, and setting up the GPIO peripheral to generate interrupts as well.
