2.1
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
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 processor allows the use of AutoHALT and Stop-Grant states which may reduce
power consumption by stopping the clock to internal sections of the processor,
for a visual representation of the
processor low power states.
