hello,

the irq line should be set by the interrupt source and cleared by the interrupt handler itself; just doing a pulse a) doesn&#39;t guarantee the interrupt will be recognised and http://forum.niosforum.com/work2/style_emoticons/<#emo_dir#>/cool.gif if the pulse is too long, the interrupt handler could be called more times than you expect.
