SVID Voltage Rail Addressing
The processor addresses 3 different voltage rail control segments within VR12.5
(V
CCIN
, V
CCD_01
, and V
CCD_23
). The SVID data packet contains a 4-bit addressing code:

Note:
1. Check with VR vendors for determining the physical address assignment method for their controllers.
2. VR addressing is assigned on a per voltage rail basis.
3. Dual VR controllers will have two addresses with the lowest order address, always being the higher phase
count.
