This involves forcing interrupts into the controller and verifying that they are recognized and can be acknowledged. This test will not succeed if the interrupt controller has been started in real mode such that interrupts cannot be forced.< p >

< p >
Allows software to simulate an interrupt in the interrupt controller. This function will only be successful when the interrupt controller has been started in simulation mode. Once it has been started in real mode, interrupts cannot be simulated. A simulated interrupt allows the interrupt controller to be tested without any device to drive an interrupt input signal into it. In Cascade mode writes to ISR of appropraite Slave controller depending on Id.< p >

< p >
Starts the interrupt controller by enabling the output from the controller to the processor. Interrupts may be generated by the interrupt controller after this function is called.< p >
It is necessary for the caller to connect the interrupt handler of this component to the proper interrupt source. This function also starts Slave controllers in Cascade mode.< p >
