If he disables the interrupt, there should be no vector to the IST in any case.
I think Jon got it. http://www.8052.com/forum/read.phtml?id=137669 He might. But I did want to make sure he knows that a low-level triggered external interrupt is going to keep firing as long as the level is low. Granted, if he disables the interrupt completely then it should not be a problem. But we haven't seen complete code so before writing off the simulator I thought it reasonable to mention a valid reason why an external interrupt would keep firing. Regards, Craig Steiner |
