Detailed Description

Driver Operations SDHC driver operations

This is the driver API structure any SDHC driver needs to define. It contains function pointers to the operations the driver implements, as well as any other driver-specific constant data.

Members marked with REQ MUST be set by the driver, whereas those marked with OPT are optional.
