P1
Maximum ITCC specification correction
The maximum I
TCC
specification has been corrected. This correction will be shown in the Voltage
and Current Specification Table # 6 and note # 7 in the Intel
®
Xeon

Processor with 512 KB L2
Cache at 1.80 GHz to 2.80 GHz Datasheet, Low Voltage Intel
®
Xeon
®
Processor at 1.60 GHz, 2.0
GHz, and 2.4 GHz Datasheet and,
Intel
®
Xeon
®
Processor with 533 MHz Front Side Bus at 2 GHz
to 3.20 GHz Datasheet.
Current table and note:
Note 7: The maximum instantaneous current the processor will draw while the thermal control circuit is active as
indicated by the assertion of PROCHOT#.
It should state:
Note 7: The maximum instantaneous current that the processor will draw while the thermal control circuit is
active as indicated by the assertion of PROCHOT# is the same as the maximum I CC for the processor.
Average Icc does drop when PROCHOT# is active, as long as the Thermal Monitor is active.
P2
Specification Clarification with respect to Time-Stamp Counter
In the “Debugging and Performance Monitoring” chapter (Section 15.8, Section 15.10.9 and
Section 15.10.9.3) of the
IA-32 Intel
®
Architecture Software Developer’s Manual, Volume 3:
System Programming Guide
, the Time-Stamp Counter definition has been updated to include
support for the future processors. This change will be incorporated in the next revision of the
IA-32
Intel
