Intel Xeon Processor with 533 MHz Front Side Bus at 2 GHz to 3.20 GHz
6.2.2
AutoHALT Powerdown State—State 2
AutoHALT is a low power state entered when the processor executes the HALT instruction. The
processor will transition to the Normal state upon the occurrence of BINIT#, INIT#, LINT[1:0]
(NMI, INTR), or an interrupt delivered over the front side bus. RESET# will cause the processor to
immediately initialize itself.
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. Both logical processors of the Intel Xeon processor with 533 MHz Front Side Bus
must be in the Stop Grant state before the deassertion of STPCLK#.
