The stop command (CMD12) can abort all data read commands at any given time. The data transfer will terminate and the card will return to the Transfer State. The read commands are block read (CMD17), multiple block read (CMD18), send write-protect (CMD30), send SCR (ACMD51) and general command in read mode (CMD56). é ÄÁÌÅÅ: In multiple-block read mode, the card sends a continuous flow of data blocks following the initial host read command. The data flow is terminated by a stop transmission command, CMD12. The Timing of Multiple Block Read Command timing diagram describes the timing of the data blocks, and the Timing of Stop Command (CMD12, Data Transfer Mode) timing diagram describes the response to a stop command.
