Thanks for that note Erik. That is indeed interesting though I have pullups enabled and the state of that I/O pin is tied high externally (interrupt is active low). Does what you're stating hold regardless of the state of the signal on the I/O pin? Either way setting EX0 "later" in the assembly seems to fix the issue. It just strikes me as strange/I'm annoyed that I don't understand why my original code doesn't work. Thanks,
