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.
