6-2
Intel Xeon Processor MP with up to 2MB L3 Cache
The return from a System Management Interrupt (SMI) handler can be to either Normal Mode or
the AutoHALT Power Down state. See the Intel Architecture Software Developer's Manual,
Volume III: System Programmer's Guide for more information.
The system can generate a STPCLK# while the processor is in the AutoHALT Power Down state.
When the system deasserts the STPCLK# interrupt, the processor will return execution to the
HALT state.
6.2.3
Stop-Grant State—State 3
When the STPCLK# pin is asserted, the Stop-Grant state of the processor is entered 20 bus clocks
after the response phase of the processor-issued Stop Grant Acknowledge special bus cycle. Once
the STPCLK# pin has been asserted, it may only be deasserted once the processor is in the Stop
Grant state. For the Intel Xeon processor MP on the 0.13 micron process processor, both logical
processors must be in the Stop Grant state before the deassertion of STPCLK#.
Since the AGTL+ signal pins receive power from the system bus, these pins should not be driven
(allowing the level to return to VCC) for minimum power drawn by the termination resistors in this
state. In addition, all other input pins on the system bus should be driven to the inactive state.
