2.11.2 V Overshoot Specification
CC
The processor can tolerate short transient overshoot events where V
voltage when transitioning from a high-to-low current load condition. This overshoot
cannot exceed VID + V
VID). These specifications apply to the processor die voltage as measured across the
VCC_SENSE and VSS_SENSE lands.
