Abstract
An Advanced Technology Attachment (ATA) device is disclosed for communicating with a host. The ATA device receives a command from the host, and while the ATA device is busy processing the command, the ATA device receives intra-command data from the host in at least one bits 3, 4, 5, and 6 in a device control field. In one embodiment the ATA device is a parallel ATA device, and the device control field is part an ATA task file. In another embodiment, the ATA device is a serial ATA device, and the device control field is part of a host to device Frame Information Structure (FIS).
