2 Low Power Features
Low Power Features
2.1 Clock Control and Low Power States
The Intel Pentium M processor supports the AutoHALT, Stop-Grant, Sleep, Deep Sleep, and
Deeper Sleep states for optimal power management. See Figure 1 for a visual representation of the
processor low-power states.

2.1.1
2.1.2
Normal State
This is the normal operating state for the processor.
AutoHALT Powerdown State
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#, LINT[1:0] (NMI,
INTR), or PSB interrupt message. RESET# will cause the processor to immediately initialize itself.
A System Management Interrupt (SMI) handler will return execution to either Normal state or the
AutoHALT Powerdown state. See the Intel Architecture Software Developer's Manual, Volume III:
System Programmer's Guide for more information.
The system can generate a STPCLK# while the processor is in the AutoHALT Powerdown state.
When the system deasserts the STPCLK# interrupt, the processor will return execution to the
HALT state.
