Clock Control and Low Power States
The Intel Celeron M processor supports the AutoHALT, Stop Grant, Sleep, and Deep Sleep states
for optimal power management. See
power states.
Normal State
This is the normal operating state for the processor.
AutoHALT Power-Down State
AutoHALT is a low-power state entered when the processor executes the HALT instruction. The
processor will transition to the Normal state upon the occurrence of SMI#, INIT#, LINT[1:0]
(NMI, INTR), or FSB interrupt message. RESET# will cause 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.
