CIE2
Queue 2 Completion Software Interrupt Enable. CIE2 enables an interrupt upon completion of
queue 2. The interrupt request is initiated when the conversion is complete for the CCW in
queue 2.
0 Disable the queue completion interrupt associated with queue 2
1 Enable an interrupt after the conversion of the sample requested by the last CCW in queue 2
1
PIE2
Queue 2 Pause Software Interrupt Enable. PIE2 enables an interrupt when queue 2 enters the
pause state. The interrupt request is initiated when conversion is complete for a CCW that has
the pause bit set.
0 Disable the pause interrupt associated with queue 2
1 Enable an interrupt after the conversion of the sample requested by a CCW in queue 2 which
has the pause bit set
2
SSE2
Queue 2 Single-Scan Enable Bit. SSE2 enables a single-scan of queue 2 to start after a trigger
event occurs. The SSE2 bit may be set to a one during the same write cycle when the MQ2 bits
are set for one of the single-scan queue operating modes. The single-scan enable bit can be
written as a one or a zero, but is always read as a zero. The SSE2 bit enables a trigger event
to initiate queue execution for any single-scan operation on queue 2. The QADC64E
clears the
SSE2 bit when the single-scan is complete. Refer to
for more information.
0 Trigger events are not accepted for single-scan modes
1 Accept a trigger event to start queue 2 in a single-scan mode
3:7
MQ2
Queue 2 Operating Mode. The MQ2 field selects the queue operating mode for queue 2. Refer
to
for more information.

RESUME
0 After suspension, begin executing with the first CCW in queue 2 or the current sub-queue
1 After suspension, begin executing with the aborted CCW in queue 2
