VID[6:1]
O
VID[6:1] (Voltage ID) pins are used to support automatic selection of power 
supply voltages (V
CC
). These are CMOS signals that are driven by the processor 
and must be pulled up through a resistor. Conversely, the voltage regulator output 
must be disabled prior to the voltage supply for these pins becomes invalid. The 
VID pins are needed to support processor voltage specification variations. See 
 for definitions of these pins. The VR must supply the voltage that is 
requested by these pins, or disable itself.
VSS_SENSE
VSS_SENSE2
O
VSS_SENSE and VSS_SENSE2 provides an isolated, low impedance connection to 
the processor core power and ground. This signal should be connected to the 
voltage regulator feedback signal, which insures the output voltage (that is, 
processor voltage) remains within specification. Please see the applicable platform 
design guide for implementation details.
VTT
P
The FSB termination voltage input pins. Refer to 
 for further details.
VTT_SEL
O
The VTT_SEL signal is used to select the correct V
TT
 voltage level for the processor. 
VTT_SEL is connected to ground on the Intel® Xeon® Processor 7400 Series 
package.
