Intel Celeron 440 HH80557RG041512 Data Sheet

Datasheet

87

Several configuration options can be configured by hardware. The processor samples 

the hardware configuration at reset, on the active-to-inactive transition of RESET#. For 

specifications on these options, refer to 

The sampled information configures the processor for subsequent operation. These 

configuration options cannot be changed except by another reset. All resets reconfigure 

the processor; for reset purposes, the processor does not distinguish between a 

"warm" reset and a "power-on" reset.

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 and can only be operated at the rated frequency.

NOTE:
1.

Asserting this signal during RESET# will select the corresponding option.

2.

Address signals not identified in this table as configuration options should not be asserted 
during RESET#.

The processor allows the use of AutoHALT and Stop-Grant states which may 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.
