6.2
Clock Control and Low Power States
The processor allows the use of AutoHALT and Stop-Grant states to reduce power 
consumption by stopping the clock to internal sections of the processor, depending on 
each particular state. See 
 for a visual representation of the processor low 
power states.
6.2.1
Normal State
This is the normal operating state for the processor.
6.2.2
HALT and Extended HALT Powerdown States
The processor supports the HALT or Extended HALT powerdown state. The Extended 
HALT powerdown must be enabled via the BIOS for the processor to remain within its 
specification. 
The Extended HALT state is a lower power state as compared to the Stop Grant State.
If Extended HALT is not enabled, the default powerdown state entered will be HALT. 
Refer to the sections below for details about the HALT and Extended HALT states.
