Core Low Power State Descriptions
2.1.1.1
Core C0 State
This is the normal operating state for cores in the processor.
2.1.1.2
Core C1/AutoHALT Powerdown State
C1/AutoHALT is a low power state entered when a core executes the HALT instruction.
The processor transitions to the C0 state upon occurrence of SMI#, INIT#, LINT[1:0]
(NMI, INTR), or FSB interrupt messages. RESET# causes the processor to immediately
initialize itself.
