(2)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.

1.5.3UNIT ATTENTION condition multiple hold

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.
