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 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 states 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.
Table 6-1.
Power-On Configuration Option Signals
Configuration Option
Signal1,2,3
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. 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.
