UNIT 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 BUS DEVICE
RESET occurred" UNIT ATTENTION condition is reported.
