Configuration and Low Power
Features
7.1
Power-On Configuration Options
Several configuration options can be configured by hardware. The mobile Celeron processor
samples its hardware configuration at reset, on the active-to-inactive transition of RESET#. For
specifications on these options, please refer to Table 39.
Frequency determination functionality will exist on engineering sample processors which means
that samples can run at varied frequencies. Production material will have the bus to core ratio
locked during manufacturing and can only be operated at the rated frequency.
The sampled information configures the processor for subsequent operation. These configuration
options cannot be changed except by another reset. All resets reconfigure the processor.
NOTE:
Asserting this signal during RESET# will select the corresponding option.
7.2
Clock Control and Low Power States
The use of AutoHALT, Stop-Grant, Sleep, and Deep Sleep states is allowed in mobile Celeron
processor based systems to reduce power consumption by stopping the clock to internal sections of
the processor, depending on each particular state. See Figure 33 for a visual representation of the
processor low-power states.
7.2.1
Normal State
This is the normal operating state for the processor.
