VID[6:0]
VID[6:0] (Voltage ID) are used to support automatic
selection of power supply voltages (VCC). Intel Atom
Processor D400 and D500 Series support only a single
fused voltage.
Refer to the appropriate platform design guide or
Voltage Regulator-Down (VRD) 11.0 Design Guidelines
for more information. The voltage supply for these
signals must be valid before the VR can supply VCC to
the processor. Conversely, the VR output must be
disabled until the voltage supply for the VID signals
become valid. The VR must supply the voltage that is
requested by the signals, or disable itself.
