a. Link
Command link is specified by this bit is "1." Details of the operation of the command link
are described in item 1.3.2.
b. Flag
This bit is valid only when "1" is specified in the Link bit. If "0" is specified in the Link
bit, "1" must not be specified in this bit.
This bit specifies the type of message sent from the TARG to the INIT when a command
which is a link specification has been completed normally. The IDD sends the LINKED
COMMAND COMPLETE WITH FLAG message when this bit is "1," and the LINKED
COMMAND COMPLETE message when this bit is "0," to the INIT.
Normally, this bit is used to generate an interrupt to software in the INIT when execution
of a specific command in a group of commands linked together in a series has been
completed.
c. Bit 7, 6 (vendor unique)
Except in cases where it is expressly specified in the individual commands, specification
of these bits has no meaning, and the IDD disregards the specified values.
Note
It is possible that bits 7 and 6 of the control byte will be used in future product
specifications as an inherent control field. It is recommended that zeros be specified
in this field.
