QADC64E Enhanced Mode Operation
The above 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 QADC64E
is actively executing CCWs. The conventional use for the freeze mode is for software/hardware
debugging. When the CPU background debug mode is enabled and a breakpoint occurs, the freeze signal
is issued, which can cause peripheral modules to stop operation. When freeze is detected, the QADC64E
completes the conversion in progress, unlike queue 1 suspending queue 2. After the freeze condition is
removed, the QADC64E 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.
