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
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
data stops two clock cycles after the end bit of the stop command.
