Datasheet
Features
A transition to the 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.
While in Stop Grant state, the processor will process snoops on the front side bus and it will latch
interrupts delivered on the front side bus.
The PBE# signal can be driven when the processor is in Stop Grant state. PBE# will be asserted if
there is any pending interrupt latched within the processor. Pending interrupts that are blocked by
the EFLAGS.IF bit being clear will still cause assertion of PBE#. Assertion of PBE# indicates to
system logic that it should return the processor to the Normal state.
7.2.4
Enhanced HALT Snoop or HALT Snoop State, Stop Grant
Snoop State
The Enhanced HALT Snoop state is used in conjunction with the Enhanced HALT state. If
Enhanced HALT state is not enabled in the BIOS, the default Snoop state entered will be the HALT
Snoop state. Refer to the sections below for details on HALT Snoop state, Grant Snoop state and
Enhanced HALT Snoop state.
7.2.4.1
HALT Snoop State, Stop Grant Snoop State
The processor will respond to snoop or interrupt transactions on the front side bus while in Stop
Grant state or in HALT Power Down state. During a snoop or interrupt 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) or the
interrupt has been latched. After the snoop is serviced or the interrupt is latched, the processor will
return to the Stop Grant state or HALT Power Down state, as appropriate.
7.2.4.2
Enhanced HALT Snoop State
The Enhanced HALT Snoop state is the default Snoop state when the Enhanced HALT state is
enabled via the BIOS. The processor will remain in the lower bus ratio and VID operating point of
the Enhanced HALT state.
While in the Enhanced HALT Snoop state, snoops and interrupt transactions are handled the same
way as in the HALT Snoop state. After the snoop is serviced or the interrupt is latched, the
processor will return to the Enhanced HALT state.
7.2.5
Sleep State
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 processor will enter the Sleep state
upon the assertion of the SLP# signal. The SLP# pin has a minimum assertion of one BCLK
period. The SLP# pin should only be asserted when the processor is in the Stop Grant state. For 64-
bit Intel Xeon processors with 2 MB L2 cache, the SLP# pin may only be asserted when all logical
processors are in the Stop Grant state. SLP# assertions while the processors are not in the Stop
Grant state are out of specification and may results in illegal operation.
