CIE2 enables completion interrupts for queue 2. The interrupt request is generated
when the conversion is complete for the last CCW in queue 2.
PIE2 enables pause interrupts for queue 2. The interrupt request is generated when
the conversion is complete for a CCW that has the pause bit set.
SSE2 enables a single-scan of queue 2 after a trigger event occurs. The SSE2 bit may
be set to a one during the same write cycle that sets the MQ2[4:0] bits for the single-
scan queue operating mode. The single-scan enable bit can be written as a one or a
zero, but is always read as a zero.
The SSE2 bit allows a trigger event to initiate queue execution for any single-scan op-
eration on queue 2. The QADC clears SSE2 when the single-scan is complete.
The MQ2 field selects the queue operating mode for queue 2. Table D-26 shows the
bits in the MQ2 field which enable different queue 2 operating modes.
0 = Queue 2 completion interrupts disabled.
1 = Generate an interrupt request after completing the last CCW in queue 2.
0 = Queue 2 pause interrupts disabled.
1 = Generate an interrupt request after completing a CCW in queue 2 which has
