13.5.7.3
This sequence sends a write data command to the card. The card sends back a response token on the CMD
line. After receiving this response, the host starts transmitting data on the DAT lines. After every data
packet, the card sends back a CRC status response, followed by a possible busy.
The sequence is set to send BLOCKCOUNT data packets to the card. No STOP command is sent as part
of this sequence.
