3. Card Management Interface
3.1 Overview
The Card Management Service provides the Host with card I/O function capability (Type-A or Type-B)
and SDIO transfer mode capability. This information can be accessed via various defined SDIO
registers.
3.2 I/O Function Capability
The I/O device interface field in the Function Basic Register (FBR) provides information on the I/O
function capability. The Host can recognize whether an inserted card is a Type-A Card or a Type-B
Card. The CIS (Card Information Structure) area provides configuration information for the Type-A card.
Please refer to the document 'SDIO Card Specification' for both FBR and CIS information. The Host
normally accesses these registers in early stages of card initialization procedure and it makes sure that
the Host can communicate with the Card. The Host will then proceed to initialize the Type-A Transport.
Refer to Appendix C for an example of the initialization procedure.
3.3 Transfer Mode Capability
The SMB (Supports MBIO) field in the Common Card Control Register (CCCR) provides Block Basis
transfer capability. The Host can recognize whether the inserted card is capable of Block Basis transfer
(optional). Please refer to 'SDIO Card Specification' for CCCR information.
