6.3.1

The Configuration Port is disabled by default and must be enabled by placing the device into CONFIG MODE. This is

done by writing the value 55h into the INDEX location. Any Reset event to the device, including PLTRST#, will again

disable the interface, requiring it to be re-enabled by this method.

The Configuration Port can also be disabled explicitly by writing the value AAh to the INDEX location. Register accesses

will be disabled until the value 55h is again written to the INDEX location. The Configuration Port still claims I/O transfers

even while disabled, so the Disabled state does not cause these transfers to be propagated to LPC.
