• Manufacturer Part Number: MC9328MX1/D
• Description: i.MX Integrated Portable System Processor
• Manufacturer: ETC

Figure 51 on page 68 shows the basic write operation timing. As with the read operation, after the card response,
the data transfer starts after N
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.
