Does what you're stating hold regardless of the state of the signal on the I/O pin?
no, an external signal driving the pin high is a form of a "pullup" (not by standard meaning of the word, but it does "pull the pin up") 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. AH, now we get a good guess at the reason. The external signal does not go high fast enough after reset. Erik |
