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.
