15 DAQCOMP Data Acquisition Complete—This bit
reflects the status of the data acquisition
termination signal. If DAQCOMP is set
and either OVERFLOW or OVERRUN
is also set, the current acquisition
sequence ended on an error condition.
If DAQCOMP is set and neither
OVERFLOW nor OVERRUN is set, the
data acquisition operation has completed
without error. When DAQCOMP is set,

indicates whether a data acquisition
operation is in progress. If DAQPROG
is set, a data acquisition operation is in
progress. If DAQPROG is cleared, the
