  • Microprocessor with OEM mode for power management with input/output intiated selection of special address space
    Patent number: 5274791
    Abstract: The present invention provides a microprocessor with a special OEM mode of operation that can be used by an OEM system integrator to implement special tasks such as power management. The OEM mode provided by the present invention is designed for use by a system integrator who integrates a microprocessor into a larger system such as a personal computer. The OEM mode of operation provided by this invention adds features to the overall system; however, it is transparent to system programmers. The system integrator can use the OEM mode to configure a system so that the system has certain special power management features, which can not be accessed by programmers who use the system. The OEM mode provided by the present invention is accessed by a signal on a special I-O pin. For example, an external timer can periodically provide signals to this special pin, thereby periodically interrupting the microprocessor and putting the microprocessor in the OEM mode.
