Specifications
Figure 50 on page 67 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
read command. If the system is in multiple block read mode, the card sends a continuous flow of data blocks with
distance N
the stop command.
