Currently I'm trying to put an interrupt in my custom component. I have one question, in the interrupt signal (in my case its type is 'interrupt sender') properties, which Avalon MM that I suppose to assign? I still confused with the 'associateAddressablePoint' meaning... :( Could you explain it to me?

I've tried to provide an Avalon MM slave consists of a 'write' and a 'writedata' signal. This Avalaon MM slave function is to let the CPU send a command to clear the interrupt bit. Then, I assign my interrupt signal in SOPC to this Avalon MM. However, the result is very strange... my program totally doesn't work, even it has hanged in the beginning.... :(

Help me..please...
