HALT Snoop State and Stop Grant Snoop State
The processor will respond to snoop transactions on the FSB while in Stop-Grant state
or in HALT Power Down state. During a snoop transaction, the processor enters the
HALT Snoop State:Stop Grant Snoop state. The processor will stay in this state until the
snoop on the FSB has been serviced (whether by the processor or another agent on the
FSB). After the snoop is serviced, the processor will return to the Stop Grant state or
HALT Power Down state, as appropriate.
