If multiple overshoots and/or multiple undershoots occur, measure the worst-case pulse duration for each magnitude
and compare the results against the AF = 1 specifications (note: multiple overshoot/undershoot events within one
clock cycle must have their pulse durations summed together to determine the total pulse duration). If all of these
worst case overshoot or undershoot events meet the specifications (measured time < specifications) in the table
where AF=1, then the system passes.

NOTES:
1.
Unless otherwise noted, all guidelines in this table apply to all Pentium® III Xeon™ processor at 600 MHz+ frequencies.
2.
Overshoot Magnitude and Undershoot Magnitude are absolute values and should never exceed 2.3V under any circumstances.
3.
Overshoot is measured relative to VSS.
4.
Undershoot is measured relative to VTT.
5.
Overshoot/Undershoot Pulse Duration is measured relative to 1.635V.
6.
Rinback below VTT cannot be subtracted from Overshoots/Undershoots.
7.
Lesser Undershoot does not allocate longer or larger Overshoot. Lesser Overshoot does not allocate longer or larger Undershoot.
8.
OEM's are encouraged to follow Intel provided layout guidelines.
9.
All values specified by design characterization.
