VID[6]
VID[5:3]/CSC[2:0]
VID[2:0]/MSID[2:0]
VID[6:0] (Voltage ID) Pins: Used to
support automatic selection of power supply
voltages (VCC). These are CMOS signals that
are driven by the processor.

CSC[2:0]/VID[5:3] - Current Sense
Configuration bits, for ISENSE gain setting.
This value is latched on the rising edge of
VTTPWRGOOD.

MSID[2:0]/VID[2:0]- Market Segment
Identification is used to indicate the
maximum platform capability to the
processor. A processor will only boot if the
MSID[2:0] pins are strapped to the
appropriate setting (or higher) on the
platform (see
Identification is used to indicate the
maximum platform capability to the
processor. A processor will only boot if the
MSID[2:0] pins are strapped to the
appropriate setting (or higher) on the
platform (see
for MSID encodings). MSID is used to help
protect the platform by preventing a higher
power processor from booting in a platform
designed for lower power processors.
MSID[2:0] are latched on the rising edge of
VTTPWRGOOD.
NOTE: VID[5:3] and VID[2:0] are bi-
directional. As an input, they are CSC[2:0]
and MSID[2:0] respectively.
