Flag, Link, and RelAdr
Many commands have bits named Flag, Link and RelAdr. The definitions
of these bits are:
A Link bit of 1 indicates that the drive links to the next command upon
successful completion of the current command. When the command is
terminated successfully, the drive returns the INTERMEDIATE/GOOD
status and the LINKED COMMAND COMPLETE or the LINKED
COMMAND COMPLETE (WITH FLAG) message depending on the state
of the Flag bit. The Flag bit may be set to 1 only when the Link bit is 1. If
this bit is set to 1 with the Link bit, the drive returns the LINKED
COMMAND COMPLETE (WITH FLAG) message upon successful
completion of the command. If this bit is set to 0, it returns the LINKED
COMMAND COMPLETE message.
The Relative Address (RelAdr) bit is set to 1 to indicate that the logical
block address of the command descriptor block is a two's complement
displacement. This negative or positive displacement is added to the
logical block address last accessed on the drive to form the logical block
address for this command.
