R2 Response Format

The first byte is identical to the response R1. The content of the second byte is described in the following:

• Out of range  csd_overwrite: This status bit has two functions. It is set if the command

argument was out of its valid range or if the host is trying to change the ROM section or reverse

the copy bit (set as original) or permanent WP bit (un-protect) of the CSD register.

• Erase param: An invalid selection, sectors or groups, for erase.

• Write protect violation: The command tried to write a write protected block.

• Card ECC failed: Card internal ECC was applied but failed to correct the data.

• CC error: Internal card controller error

• Error: A general or an unknown error occurred during the operation.

• Write protect erase skip | lock/unlock command failed: This status bit has two functions

overloaded. It is set when the host attempts to erase a write protected sector or if a sequence or

password error occurred during card lock/unlock operation.

• Card is locked: Set when the card is locked by the user. Reset when it is unlocked.
