processor in the 423-pin package. If the processor socket is empty (VID[4:0] = 11111), or
the voltage regulation circuit cannot supply the voltage that is requested, it must disable
itself. See the Intel® Pentium® 4 Processor VR-Down Design Guidelines for more details.
Power source characteristics must be guaranteed to be stable whenever the supply to the
voltage regulator is stable.
