Processor Core Voltage Identification Code - Intel Itanium 2 Processor Datasheet

The power pod provides a selectable output voltage controlled via multiple binary weighted
Voltage Identification (VID) inputs. The VID value (high = 1; low = 0) is defined in
VID pads shall be considered as LVTTL inputs to the power pod, having resistive pull-ups (5 kΩ)
included inside the power pod to the internal 3.3 V power supply. The VID pads on the power
connector tab will be pulled low with 10 Ω resistors that are internal to the processor. The 10 Ω
resistive pulldowns are controlled by Intel and will not be externally adjustable.
