"Reset the DA" is to disable the pixel interrupt, i.e.,
iccExec [activeList] readoutAbort
We try to keep the camera reading out all the time, which means it
is always sending pixels.
The amplifier voltage check comes after the DA is sent the readoutBegin
command but before the camera is told to start reading out (it is stopped
at the beginning of goDrift or goStare so iop has control over the first
pixel).
I think some of the confusion John ran into last night is that after
the goDrift failed no-one (neither John nor iop) sent a readoutAbort.
At least, none was recorded in the murmur log.
John then iacked the camera, which starts it scanning.  The DA was
still sitting there ready for pixels, so it started reading.
Note that choice 2 works just fine, so we should get ride of the
qualifier.  And, I guess we should check what goDrift does if one
selects option 3.
