MCF5282 and MCF5216 ColdFire Microcontroller User’s Manual, Rev. 3
Queue 2 completion software interrupt enable. Enables an interrupt request upon
completion of queue 2. The interrupt request is initiated when the conversion is
complete for the last CCW in queue 2.
1 Enable queue 2 completion interrupt.
0 Disable queue 2 completion interrupt.
Queue 2 pause interrupt enable. Enables an interrupt request 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.
1 Enable the queue 2 pause interrupt.
0 Disable the queue 2 pause interrupt.
Queue 2 single-scan enable. Enables a single-scan of queue 2 after a trigger event
occurs. SSE2 may be set during the same write cycle that sets the MQ2 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
SSE2 when the single-scan is complete.
1 Allow a trigger event to start queue 2 in a single-scan mode.
0 Trigger events are ignored for queue 2 single-scan modes.
Selects the operating mode for queue 2.
which enable different queue 2 operating modes.
Selects the resumption point for queue 2 after its operation is suspended due to a
queue 1 trigger event. If RESUME is changed during the execution of queue 2, the
change is not recognized until an end-of-queue condition is reached or the operating
mode of queue 2 is changed.
1 After suspension, begin execution with the aborted CCW in queue 2.
0 After suspension, begin execution with the first CCW of queue 2 or the current
Beginning of queue 2. Denotes the CCW location where queue 2 begins. This allows
the length of queue 1 and queue 2 to vary. The BQ2 field also serves as an
end-of-queue condition for queue 1.
