16.4.3.2.2.1. Stream Data Read
An open‑ended stream‑read data transfer occurs if the bytcnt register is set to 0. During this type of data transfer, the data path continuously receives data in a stream until the host software issues an SD/SDIO STOP command. A stream data transfer terminates two clock cycles after the end bit of the STOP command.†
If the bytcnt register contains a nonzero value and the send_auto_stop bit in the cmd register is set to 1, a STOP command is internally generated and loaded into the command path, where the end bit of the STOP command occurs after the last byte of the stream data transfer is received. This data transfer can terminate if the host issues an SD/SDIO STOP or STOP_TRANSMISSION (CMD12) command before all the data bytes are received from the card.†
