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.
