ABSTRACT:
A circuit for selectively invoking a particular interrupt service routine to handle a particular interrupt request. The present invention includes a programmable register with one or more bits per interrupt request input. The present invention also includes interrupt selection logic which outputs a particular interrupt in response to an interrupt request input and data stored in the programmable register. The interrupt then invokes the associated interrupt service routine to handle the interrupt request. The present invention is used to choose the interrupt service routine to handle a particular interrupt request from any source within the computer system in any computer system operating mode.
