Features
This chapter contains power-on configuration options and clock control/low power state
descriptions.
6.1
Power-On Configuration Options
Several configuration options can be configured by hardware. The Celeron D processor in the
775-land package samples the hardware configuration at reset, on the active-to-inactive transition
of RESET#. For specifications on these options, refer to Table 6-1.
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.
6.2
Clock Control and Low Power States
The processor allows the use of AutoHALT and Stop-Grant to reduce power consumption by
stopping the clock to internal sections of the processor, depending on each particular state. See
Figure 6-1 for a visual representation of the processor low power states.
