Figure 50. Timing Diagrams at Data Read
Figure 51 shows the basic write operation timing. As with the read operation, after the card response, the
data transfer starts after NWR cycles. The data is suffixed with CRC check bits to allow the card to check
for transmission errors. The card sends back the CRC check result as a CC status token on the data line. If
there was a transmission error, the card sends a negative CRC status (101); otherwise, a positive CRC
status (010) is returned. The card expects a continuous flow of data blocks if it is configured to multiple
block mode, with the flow terminated by a stop transmission command.
