Features

6.1

Power-On Configuration Options

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 Table 31.

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 states to reduce power

consumption by stopping the clock to internal sections of the processor, depending on

each particular state. See Figure 21 for a visual representation of the processor low

power states.

Table 31.

Power-On Configuration Option Signals

Configuration Option

Signal1,2,3

NOTES:

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

Address signals not identified in this table as configuration options should not

be asserted during RESET#.

Disabling of any of the cores within the processor must be handled by

configuring the EXT_CONFIG Model Specific Register (MSR). This MSR will allow

for the disabling of a single core per die within the package.
