I am using AT89C51RC2 microcontroller. I do not obtain iterrupt respond for spi. x2 and other features are correct. Controller is correctly programmed (it is working correctly), however, in simulation mode execution sequence never enters in spi interrupt code (9). Therefore, I am not able to debug interrupt sequence.
Controller is correctly programmed ... I am not able to debug interrupt sequence. Why do you need to debug something "correctly programmed" Erik
