A time separator is provided between the triggers and the end of
conversion (EOC). The relationship to QCLK displayed is not
guaranteed.
CWPQ1 and CWPQ2 typically lag CWP and only match CWP when the
associated queue is inactive. Another way to view CWPQ1 and CWPQ2
is that these registers update when EOC triggers the write to the result
register.
For the CCW with the pause bit set (CCW0), CWP does not increment
until triggered. For the CCW with the pause bit clear (CCW1), the CWP
increments with the EOC.
The conversion results Q1 RESx show the result associated with CCWx,
such that R0 represents the result associated with CCW0.

single-scan with same assumptions in example 1 except:
When the gate closes and opens again, the conversions start with the
first CCW in Q1.
When the gate closes, the active conversion completes before the
queue goes idle.
When Q1 completes, both the CF1 bit sets and the SSE bit clears.
In this mode, the PF1 bit sets to reflect that a gate closing occurred
before the queue completed.

continuous scan mode with the same assumptions as in
At the end of Q1,the completion flag CF1 sets and the queue restarts. If
the queue starts a second time and completes, the trigger overrun flag
TOR1 sets.
