Pentium III Processor for the PGA370 Socket up to 750 MHz
2.2.1
Normal State—State 1
This is the normal operating state for the processor.
2.2.2
AutoHALT Powerdown State—State 2
AutoHALT is a low power state entered when the processor executes the HALT instruction. The
processor transitions to the Normal state upon the occurrence of SMI#, INIT#, or LINT[1:0] (NMI,
INTR). RESET# causes the processor to immediately initialize itself.
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.
FLUSH# is serviced during the AutoHALT state, and the processor will return to the AutoHALT
state.
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 returns execution to the HALT
state.
2.2.3
Stop-Grant State—State 3
The Stop-Grant state on the processor is entered when the STPCLK# signal is asserted.
Since the AGTL+ signal pins receive power from the system bus, these pins should not be driven
(allowing the level to return to VTT) 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.
BINIT# and FLUSH# are not serviced during the Stop-Grant state.
RESET# causes the processor to immediately initialize itself, but the processor stays in Stop-Grant
state. A transition back to the Normal state occurs with the deassertion of the STPCLK# signal.
A transition to the HALT/Grant Snoop state occurs when the processor detects a snoop on the
system bus (see Section 2.2.4). A transition to the Sleep state (see Section 2.2.5) occurs with the
assertion of the SLP# signal.
While in Stop-Grant State, SMI#, INIT#, and LINT[1:0] are latched by the processor, and only
serviced when the processor returns to the Normal state. Only one occurrence of each event is
recognized and serviced upon return to the Normal state.
2.2.4
HALT/Grant Snoop State—State 4
The processor responds to snoop transactions on the system 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 stays in this state until the snoop on the system bus has been serviced
(whether by the processor or another agent on the system bus). After the snoop is serviced, the
processor returns to the Stop-Grant state or AutoHALT Power Down state, as appropriate.
