Abstract
Level trigger mode interrupts are converted to edge trigger mode interrupts in a computer system. A circuit detects the occurrence of a level trigger mode interrupt request, and asserts an edge trigger mode interrupt request output. The edge trigger mode interrupt request remains asserted until an End of Interrupt input is asserted, indicating that the CPU has completed servicing the prior interrupt. The edge trigger mode interrupt request is then deasserted.
