60 Datasheet

Once a target frequency/bus ratio is resolved, the processor core will transition to the

new target automatically.

 On an upward operating point transition, the voltage transition precedes the

frequency transition.

 On a downward transition, the frequency transition precedes the voltage transition.

When transitioning to a target core operating voltage, a new VID code to the voltage

regulator is issued. The voltage regulator must support dynamic VID steps to support

this method.

During the voltage change:

 It will be necessary to transition through multiple VID steps to reach the target

operating voltage.

 Each step is 12.5 mV for Intel MVP-6.5 compliant VRs.

 The processor continues to execute instructions. However, the processor will halt

instruction execution for frequency transitions.
