Card Configuration
The CompactFlash Memory Card is identified by information in the Card Information
Structure (CIS). The Card has four configuration registers
●
●
●
●
They are used to coordinate the I/O spaces and the Interrupt level of cards that are located
in the system. In addition, in I/O Card mode these registers provide a method for accessing
status information that would normally appear on dedicated pins in Memory Card mode.
The base address of the card configuration registers is 200h in the Attribute Memory space.
No write operation should be performed to the attribute memory area except for the
configuration register addresses. All other attribute memory locations are reserved. See
Section 6.5: Attribute Memory
CompactFlash Memory Card Registers and Memory Space Decoding
