PIE1 — Queue 1 Pause Interrupt Enable Bit
SSE1 — Queue 1 Single-Scan Enable Bit
MQ1[12:8] — Queue 1 Operating Mode Field
MQ1[12:8]
PIE1 enables an interrupt request 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.
SSE1 enables a single-scan of queue 1 after a trigger event occurs.
SSE1 may be set during the same write cycle that sets the MQ1 bits
for one of the single-scan queue operating modes. The single-scan
enable bit can be written to 1 or 0, but is always read as a 0, unless
the QADC is in test mode. The QADC clears SSE1 when the
single-scan is complete.
The MQ1 field selects the operating mode for queue 1.
