2.4 Card Configuration
The CompactFlash cards are identified by appropriate information in the Card Information Structure (CIS). The fol-
lowing 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 Compact-
Flash 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 from the CIS locations 0000H to 0198H. No writes should be per-
formed to the CompactFlash card attribute memory except to the card configuration register addresses. All other attribute memory loca-
tions are reserved.
