Intel Xeon Processor with 512 KB L2 Cache

7.2.3
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 512 KB L2 cache must be
in the Stop Grant state before the deassertion of STPCLK#.
Since the AGTL+ signal pins receive power from the front side 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 front side bus should be driven to the inactive state.
BINIT# will be recognized while the processor is in Stop-Grant state. If STPCLK# is still asserted
at the completion of the BINIT# bus initialization, the processor will remain in Stop-Grant mode. If
the STPCLK# is not asserted at the completion of the BINIT# bus initialization, the processor will
return to Normal state.
RESET# will cause the processor to immediately initialize itself, but the processor will stay in
Stop-Grant state. A transition back to the Normal state will occur with the deassertion of the
STPCLK# signal. When re-entering the Stop-Grant state from the sleep state, STPCLK# should
only be deasserted one or more bus clocks after the deassertion of SLP#.
A transition to the HALT/Grant Snoop state will occur when the processor detects a snoop on the
front side bus (see Section 7.2.4). A transition to the Sleep state (see Section 7.2.5) will occur with
the assertion of the SLP# signal.
While in the Stop-Grant state, SMI#, INIT#, BINIT# and LINT[1:0] will be latched by the
processor, and only serviced when the processor returns to the Normal state. Only one occurrence
of each event will be recognized upon return to the Normal state.
7.2.4
HALT/Grant Snoop State—State 4
The processor will respond to snoop transactions on the front side bus while in Stop-Grant state or
in AutoHALT Power Down state. During a snoop transaction, the processor enters the HALT/Grant
Snoop state. The processor will stay in this state until the snoop on the front side bus has been
serviced (whether by the processor or another agent on the front side bus). After the snoop is
serviced, the processor will return to the Stop-Grant state or AutoHALT Power Down state, as
appropriate.
7.2.5
Sleep State—State 5
The Sleep state is a very low power state in which each processor maintains its context, maintains
the phase-locked loop (PLL), and has stopped most of internal clocks. The Sleep state can only be
entered from Stop-Grant state. Once in the Stop-Grant state, the SLP# pin can be asserted, causing
the processor to enter the Sleep state. The SLP# pin is not recognized in the Normal or AutoHALT
states.
Snoop events that occur while in Sleep state or during a transition into or out of Sleep state will
cause unpredictable behavior.
