The data transfer starts N
received. The bus transaction is identical to that of a write block command (see Figure “Timing of The
Block Write Command”). As the data transfer is not block-oriented, the data stream does not include the
CRC checksum. Consequently the host can not receive any CRC status information from the card. The
data stream is terminated by a stop command. The bus transaction is identical to the write block option
when a data block is interrupted by the stop command (see Figure “Stop Transmission During Data
Transfer From The Host”).
CMD
The host must first tag the group to erase. The tagged group(s) are erased in parallel by using the CMD35,
CMD36 and CMD38. The card busy signaling is also used for the indication of the card erase procedure
duration. In this case the end of the card busy signaling also does mean that the erase of all tagged groups
has been finished. The host can (also) request the card to send the actual card state using the CMD13.
