This is the seventh ATA/ATAPI standard. Released in 2003.
This standard specifies the AT Attachment Interface between host systems and storage devices. It provides a common attachment interface for systems manufacturers, system integrators, software suppliers, and suppliers of intelligent storage devices.
The application environment for the AT Attachment Interface is any host system that has storage devices contained within the processor enclosure.
Volume 1 defines the register delivered commands used by devices implementing the standard.
Volume 2 defines the connectors and cables for physical interconnection between host and storage device, the electrical and logical characteristics of the interconnecting signals, and the protocols for the transporting commands, data, and status over the interface for the parallel interface.
Volume 3 defines the connectors and cables for physical interconnection between host and storage device, the electrical and logical characteristics of the interconnecting signals, and the protocols for the transporting commands, data, and status over the interface for the serial interface.
