NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. V is defined as the maximum voltage level at a receiving agent that will be interpreted as a logical low
IL
value.
3. V is defined as the minimum voltage level at a receiving agent that will be interpreted as a logical high
IH
value.
4. V and V may experience excursions above V
