| 11 | CMD55 assumed to be nonexistent for MMC |
---|
| 12 | |
---|
| 13 | The controller FSM assumes that MMC cards result with |
---|
| 14 | "Illegal Command" from CMD55. The card will be detected as an MMC once CMD55 |
---|
| 15 | has been accepted. However, the MMC standard defines this command, |
---|
| 16 | thus it is not save to rely on its nonexistence. Instead also a path from |
---|
| 17 | ACMD41 to CMD1 should be established. |
