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 33.
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.
Table 33.
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.
