16.5.9.3. ATA Payload Transfer Using the RW_MULTIPLE_BLOCK (RW_BLK) Command

This command involves data transfer between the CE‑ATA card device and the controller. To send a data command, the controller needs a command argument, total data size, and block size. Software receives or sends data through the FIFO buffer. †
