INQUIRY command

The INQUIRY command is executed normally, but the UNIT ATTENTION condition is not cleared.

(3)

REQUEST SENSE command

One of the following operations is performed depending on whether or not the IDD is in the sense
data hold state (shown in Section 1.6).

a.

In the case of a Sense Data Hold state

The IDD executes the REQUEST SENSE command normally and sends the sense data which
are being held to the INIT.  In this case, the UNIT ATTENTION condition is not cleared.

b. In the case of a State other than a Sense Data Hold state

The IDD executes the REQUEST SENSE command normally and sends the sense data which
indicate the UNIT ATTENTION condition and are being held to the INIT.  At this time, the
UNIT ATTENTION condition for that INIT is cleared.

If any UNIT ATTENTION condition is generated and a new UNIT ATTENTION condition is
generated for a different reason before the INIT for which the first UNIT ATTENTION condition
was held clears it, those UNIT ATTENTION conditions are held together, and the IDD reports
these multiple UNIT ATTENTION conditions in sequence.  For example, a “Mode parameters
changed,” “Spindle Synchronized” or “Spindle not Synchronized” or other UNIT ATTENTION
condition may be reported after the “Power on, RESET or TARGET RESET occurred” UNIT
ATTENTION condition is reported.
