The previous situations cover normal overlap conditions that arise with
asynchronous trigger events on the two queues. An additional conflict to
consider is that the freeze condition can arise while the QADC is actively
executing CCWs. The conventional use for the debug mode is for
software/hardware debugging. When the CPU enters background
debug mode, peripheral modules can cease operation. When freeze is
detected, the QADC completes the conversion in progress, unlike the
abort that occurs when queue 1 suspends queue 2. After the freeze
condition is removed, the QADC continues queue execution with the
next CCW in sequence.
Trigger events that occur during freeze are not captured. When a trigger
event is pending for queue 2 before freeze begins, that trigger event is
remembered when the freeze is passed. Similarly, when freeze occurs
while queue 2 is suspended, after freeze, queue 2 resumes execution as
soon as queue 1 is finished.
