SD_CMD_RESERVED

#define SD_CMD_RESERVED   (32)

Common SD_control() command code reservation offset. SD driver implementations should offset command codes with SD_CMD_RESERVED growing positively.

Example implementation specific command codes:

#define SDXYZ_CMD_COMMAND0    (SD_CMD_RESERVED + 0)
#define SDXYZ_CMD_COMMAND1    (SD_CMD_RESERVED + 1)

SD_STATUS_RESERVED

#define SD_STATUS_RESERVED   (-32)

Common SD_control status code reservation offset. SD driver implementations should offset status codes with SD_STATUS_RESERVED growing negatively.

Example implementation specific status codes:

#define SDXYZ_STATUS_ERROR0    (SD_STATUS_RESERVED - 0)
#define SDXYZ_STATUS_ERROR1    (SD_STATUS_RESERVED - 1)
#define SDXYZ_STATUS_ERROR2    (SD_STATUS_RESERVED - 2)
