Several configuration options can be configured by hardware. The Intel

®

 Pentium

®

 D 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.

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.

The Pentium D processor includes support for the Enhanced HALT powerdown state. Refer to 

 and the following sections.

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#.
