SVID_ALERT#
sVID Alert: Used by the VR to signal the prior request
has not reach the requested operating point.

SVID_DATA
sVID Data: Used by
Intel Atom Processor D2000
series and N2000 series
processor to send request
and data to the VR and then by the VR to respond.
Data is driven with a 12.5 Ohms Pull Down.

SVID_CLK
sVID Clock: sVID request are driven out on
SVID_DATA using this as the clock and are then
registered in the VR using this for the clock. When
the VR responds with data on SVID_DATA, it also
uses this clock (still sent by
Intel Atom Processor
D2000 series and N2000 series
processor) to
drive the data. This means the VR starts driving
data/alert using a clock that is late (by the
Intel
Atom Processor D2000 series and N2000 series
processor->VR flight time + VR setup time).
Clock is driven with a 12.5 Ohms PD.
Frequency: 25 MHz when using DDR3-800 26 MHz
