Specifications
Figure 27. Timing Diagrams at Data Transfer Mode
Figure 28 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 NAC, 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 NAC until the card sees a stop transmission command. The
data stops two clock cycles after the end bit of the stop command.
