Figure 41 on page 53 shows basic read operation timing. In a read operation, the sequence starts with a
single block read command (which specifies the start address in the argument field). The response is sent
on the SD_CMD lines as usual. Data transmission from the card starts after the access time delay N
beginning from the last bit of the read command. If the system is in multiple block read mode, the card
sends a continuous flow of data blocks with distance N
The data stops two clock cycles after the end bit of the stop command.
