Data read timings
The timing diagram for deselecting the card by de-asserting CS after the last card response
corresponds to a standard command-to-response timing diagram as illustrated in
During open-ended multiple block read operations, the STOP_TRANSMISSION command
may be sent while the card is transmitting data to the host. In this case, the card stops
transmitting the data block within two clock cycles (the bits in the first byte may not all be set
to '1') and returns the response message after a time measured in numbers of clock cycles
