Abstract
Accordingly, provided is an apparatus and method for generating a computer system interrupt emulation having the effect of a hardwired interrupt. A service processor with a test circuit interface can be coupled to an integrated circuit, which has a test circuit with an access to a register of the integrated circuit. A program, executable by the processor, responds to an interrupt request by instructing the processor to save a system state of the integrated circuit and to set a system state of the integrated circuit. The method for emulating an interrupt of an integrated circuit provides for receiving an interrupt request. A register of an integrated circuit is then accessed through a test circuit of the integrated circuit. The contents of the register are saved to a storage location, and the register is then set to a state responsive to the interrupt request. The interrupt request may be made locally or remotely.
