scope:

This standard defines a protocol for the transport of commands and data over High Performance Serial Bus, as specified by ANSI/IEEE 1394-1995 [B8] as amended by ANSI/IEEE 1394a-2000 [B9] and ANSI/IEEE 1394b-2002 [B10] (collectively IEEE 1394). The transport protocol, Serial Bus Protocol 3 (SBP-3), requires implementations to conform to the aforementioned standards as well as to IEEE Std 1212-2001, Control and Status Register (CSR) Architecture for microcomputer buses [B6], and permits the exchange of commands, data and status between initiators and targets connected to Serial Bus.

This standard is an evolutionary extension of ANSI INCITS 325-1998, Serial Bus Protocol 2 (SBP-2) [B2], which revises and extends its protocols to take advantage of implementation experience gained subsequent to the development of SBP-2, the continued evolution of High Performance Serial Bus, IEEE 1394, as well as other IEEE Serial Bus standards in development.
