Description
0
CIE1
Queue 1 Completion Interrupt Enable. CIE1 enables an interrupt upon completion of
queue 1. The interrupt request is initiated when the conversion is complete for the CCW in
queue 1.
0 Disable the queue completion interrupt associated with queue 1
1 Enable an interrupt after the conversion of the sample requested by the last CCW in
queue 1
1
PIE1
Queue 1 Pause Interrupt Enable. PIE1 enables an interrupt when queue 1 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 1
1 Enable an interrupt after the conversion of the sample requested by a CCW in queue 1
which has the pause bit set
2
SSE1
Queue 1 Single-Scan Enable Bit. SSE1 enables a single-scan of queue 1 to start after a
trigger event occurs. The SSE1 bit may be set to a one during the same write cycle when
the MQ1 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 SSE1 bit
enables a trigger event to initiate queue execution for any single-scan operation on queue
1. The QADC64E
clears the SSE1 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 1 in a single-scan mode

MQ1
Queue 1 Operating Mode. The MQ1 field selects the queue operating mode for queue 1.
shows the bits in the MQ1 field which enable different queue 1 operating mode
