Queued Analog-to-Digital Converter (QADC)
28.9.3
This section contains some conversion timing examples.
conversions where it is assumed that:
Recall that when QS = 0, both queues are disabled; when QS = 8, queue 1 is active and queue 2 is idle;
and when QS = 4; queue 1 is paused and queue 2 is disabled.

Q1 begins with CCW0 and ends with CCW3.
CCW0 has pause bit set.
CCW1 does not have pause bit set.
External trigger rising edge for Q1
CCW4 = BQ2 and Q2 is disabled.
Q1 RES shows relative result register updates.
