Hi Every one,
Disabled interrupts, the program will be called accidentally when running, What occasions can cause this situation?
Is this related to your other thread?
I am interpreting your reference to "illegal interrupt" as the Illegal-Instruction trap interrupt. This is triggered when the CPU tries to execute an invalid instruction.
Disabled interrupts are masked under normal operation and there is typically no way for the system to trigger them. Exceptions would be the INTR instruction that you encountered in the other thread, or an improper implementation of nested interrupts.
