Arduino and Wiz550io with Int

Question

I'm trying to use the Wiz550io in interrupt mode. I assume that the Wiz550io sets Intn low when it needs service, but I never can see the Intn pin change from high state. If I need to set some register(s), could you please explain how to do that in Arduino with Ethernet3 library Oor other)?

Thanks a lot for that, but I am still having trouble... Your code sample compiled which was a welcome first step :) When I read the datasheet it shows the IMR at 0x16 and not 0x00 like in your example code...? When I tried replacing 0x00 with 0x16 it still didn't react as expected. I replaced your ''SS'' with my Wiz CS output. Still not working. I don't know what you mean with the ''SS'' parameter...? I also need to understand how to clear the INT after I get it; could you please provide sample code for that too? Finally, I need the Wiz550io to interrupt based on a normal UDP receive transaction; I saw a few other options but none just this basic interrupt.
