to start-up VID values. Details of the SVI Bus protocol are
provided in the AMD Design Guide for Voltage Regulator
Controllers Accepting Serial VID Codes specification.
Once the set VID command is received, the ISL6324
decodes the information to determine which plane and the
VID target required. See Table 4. The internal DAC circuitry
steps the required output plane voltage to the new VID level.
During this time one or both of the planes could be targeted.
In the event the core voltage plane, VDD, is commanded to
power off by serial VID commands, the VDDPWRGD signal
If the PWROK input is de-asserted, then the controller steps
both VDD and VDDNB planes back to the stored
Pre-PWROK metal VID level in the holding register from
initial soft-start. No attempt is made to read the SVC and
SVD inputs during this time. If PWROK is reasserted, then
the on-board SVI interface waits for a set VID command.
If VDDPWRGD deasserts during normal operation, both
voltage planes are powered down in a controlled fashion.
The internal DAC circuitry stair steps both outputs down to
near zero.
remains asserted. The Northbridge voltage plane must
remain active during this time.
