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.
