The meaning of the status bits is defined as follows:
‘010’ - Data accepted.
‘101’ - Data rejected due to a CRC error.
’110’ - Data Rejected due to a Write Error
In case of any error (CRC or Write Error) during Write Multiple Block operation, the host shall abort the operation using the
“Stop Tran” Token. In case of Write Error (response ‘110’) the host should send CMD13 (SEND_STATUS) in order to get
the cause of the write problem.
Read and write commands have data transfers associated with them. Data is being transmitted or received via data
tokens. All data bytes are transmitted MSB first.
Data tokens are 4 to (N + 3) bytes long (Where N is the data block length set using the SET_BLOCK_LENGTH Command)
and have the following format:
• First byte:
• Bytes 2 - (N + 1): User data
• Last two bytes: 16 bit CRC.
If a read operation fails and the card cannot provide the required data, it will send a data error token instead. This token is
one byte long and has the following format:

7.20 Data Token Error
