Hi dsl,

Is it possible that the interrupt register is already in active condition in the beginning program? Somehow I found that somehow my interrupt register was in active condition (the actual interrupt condition didn't happen yet). I tried to clear the interrupt register in the beginning of my program, but it didn't work (it seems because the write signal came late)..

I've checked my component hardware many times, there is nothing wrong with it :(

Please help me if you know what caused this problem..

Thanks
