VIDSOUT

VIDSCLK

VIDALERT#

VIDALERT#, VIDSCLK, and VIDSCLK comprise a three signal 

serial synchronous interface used to transfer power 

management information between the processor and the 

voltage regulator controllers. This serial VID interface replaces 

the parallel VID interface on previous processors.

VCC_SENSE
VSS_SENSE

VCC_SENSE and VSS_SENSE provide an isolated, low 

impedance connection to the processor core voltage and 

ground. They can be used to sense or measure voltage near the 

silicon.
