Hi,
Erik, drop that bible to trashcan, sorry (= That chapter which explains Interrupts, says: - When the service routine is vectored to, hardware clears the flag that generated an external interrupt only if the interrupt was transition activated. If the interrupt was level-activated, then the external requesting source (rather than the on-chip hardware) controls the request flag. By the other words, if the IT0[IT1] is cleared then IE0[IE1] is the image of logical level presented on the /INT0[/INT1] pin. cu |
