Serial VID Interface (SVI)
The on-board Serial VID interface (SVI) circuitry allows the
processor to directly drive the core voltage and Northbridge
voltage reference level within the ISL6323. The SVC and SVD
states are decoded with direction from the PWROK and
VFIXEN inputs as described in the following sections. The
ISL6323 uses a digital to analog converter (DAC) to generate a
reference voltage based on the decoded SVI value. See
Figure 7 for a simple SVI interface timing diagram.
