CARD CONFIGURATION
The PC Cards are identified by appropriate information in the Card Information Structure (CIS). The
following 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 PC 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.
