Attention Condition - Fujitsu MCE3064SS Product Manual

Figure 7.16 ATTENTION condition
IMPORTANT
The ATTENTION condition generated by the INIT in the SELECTION
phase determines the message level to be used in the command
execution sequence. (Details are explained in Subsection 2.1.3.) If
the ATTENTION condition is not generated in the SELECTION phase,
the TARG uses a COMMAND COMPLETE message only. The TARG
does not respond to the ATTENTION condition even if it was
generated in the subsequent bus phase. Therefore, the TARG does not
enter the MESSAGE OUT phase.
