Hi Folks,

I'll try this question again as my post of Dec 15th didn't receive any
replies.

What would cause the INT0 to continually fire even if the pin was
grounded?  I have the set to trigger on rising edge (MCUCR = 0x03) but
it will keep triggering.  I have also tried to set it to "any logical
change" (MCUCR = 0x01) but get the same results.

Anybody have any ideas why a pin that is grounded would trigger an
interrupt?

Thanks,

Richard Cooke
