Clock Control Architecture
The Mobile Intel Celeron Processor clock control architecture (Figure 1) has been optimized for leading
edge mobile computer designs. The clock control architecture consists of six different clock states:
Normal, Auto Halt, Quick Start, HALT/Grant Snoop and Deep Sleep states. The Auto Halt state
provides a low-power clock state that can be controlled through the software execution of the HLT
instruction. The Quick Start state provides a very low power and low exit latency clock state that can be
used for hardware controlled “idle” computer states. The Deep Sleep state provides extremely low-
power states that can be used for “Power-On-Suspend” computer states, which is an alternative to
shutting off the processor’s power. The exit latency of the Deep Sleep state is 30 msec in the Mobile
Intel Celeron Processor. Performing state transitions not shown in Figure 1 is neither recommended nor
supported. Figure 2 provides the clock state characteristics, which are described in detail in the following
sections.

2.2.2 Normal
State
The Normal state of the processor is the normal operating mode where the processor’s core clock is
running and the processor is actively executing instructions.
running and the processor is actively executing instructions.
2.2.3 Auto
Halt
State
This is a low-power mode entered by the processor through the execution of the HLT instruction. A
transition to the Normal state is made by a halt break event (one of the following signals going active:
NMI, INTR, BINIT#, INIT#, RESET#, FLUSH#, or SMI#).
