with an error token rather than a data block.

4.10.4 Data Write Overview
The SPI mode supports single block and Multiple block write commands. Upon reception of a valid write
command (CMD24 or CMD25), the card will respond with a response token and will wait for a data block
to be sent from the host. CRC suffix, block length and start address restrictions are identical to the read
operation (see Figure 46). If a CRC error is detected it will be reported in the data-response token and
the data block will not be programmed. Every data block has a prefix of ‘Start Block’ token (one byte).
After a data block has been received, the card will respond with a data-response token. If the data block
has been received without errors, it will be programmed. As long as the card is busy programming, a
continuous stream of busy tokens will be sent to the host (effectively holding the DataOut line low).
Figure 4-6 Single Block Write Operation
In Multiple Block write operation the stop transmission will be done by sending ‘Stop Tran’ token instead
of ‘Start Block’ token at the beginning of the next block.
Two types of multiple block write transactions, identical to the multiple block read, are defined (the host
can use either one at any time):
* Open-ended Multiple block write
