VID
Control of the output voltage of the regulator is set from the
external six bit VID [5:0] input pins. After power-up, the VID
inputs are sampled and this value is used as the final output
voltage for the Soft Start process. After Soft Start is
complete, the internal VID setting may be changed by
modifying the external six bit VID [5:0] input pins or via the
host interface write to the internal VID register. To allow for
host interface control of VID requires that a separate register
is needed for the value of the external VID input pins. This is
needed to separately track changes to the VID set by the
host interface and the VID set from the external pins. The
same method of output voltage stepping that is used in the
Soft Start process is also applied to dynamic VID changes.
Custom VID
The ISL6590 has additional registers for a custom VID table
to be created and stored in memory locations 0940-097F.
