Queued Analog-to-Digital Converter (QADC)
Situations S10 and S11
detected for queue 2 while the queue is suspended, the trigger overrun error bit is set, the same as if queue
2 were being executed when a new trigger event occurs. Trigger overrun on queue 2 thus allows the user
to know that queue 1 is taking up so much QADC time that queue 2 trigger events are being lost.
