Power-On Configuration Options
Several configuration options can be configured by hardware. Celeron processor on 0.13 micron
process sample their 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.

Clock Control and Low Power States
The use of AutoHALT, Stop-Grant, and Sleep states is allowed in Celeron processor on
0.13 micron process based systems to reduce power consumption by stopping the clock to internal
sections of the processor, depending on each particular state. See
