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
