Intel PentiumD 950 HH80553PG0964M User Manual

91

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, please 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.

NOTES:
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#.

3.

This mode is not tested

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.
