SanDisk CompactFlash Memory cards are identified by appropriate information
in the Card Information Structure (CIS). The configuration registers are used
to coordinate the I/O spaces and the interrupt level of cards that are located in
the system.
In addition, these registers provide a method for accessing status information
about the card that may be used to arbitrate between multiple interrupt
sources on the same interrupt level, or to replace status information that
appears on dedicated pins in memory cards that have alternate use in I/O
cards.
Note: The location of the card configuration registers should always be read

DEVICE data. A device implementation shall support any legal host
implementation.
This parameter specifies the time from the negation edge of /IORD to the
time that the data bus is no longer driven by the device (tri-state).
