Data overwrite error status (DOWE) [D2]
Value "1" set to the status indicates that readable conversion data
has been overwritten during clock-mode operation, because
intervals of sampling clock are longer than data input intervals. If
this status is detected, sampling clock interval must be expanded or
reading intervals must be shortened. The status is cleared when no
more overwritten data exists.

error status
Sampling clock input status (SCI) [D4]
The status is set to "1" if a sampling clock is input after outputting
sampling start command in clock mode. The value is cleared after
the status is read. *
Sampling clock error status (SCE) [D5]
The status is set to "1" if a sampling data is clocked during
sampling operation in clock mode. The value is cleared after the
status is read. * The sampling clock input during sampling
operation is ignored.
* Each status is also cleared to "0" under the following conditions:
- Upon output of initialization command.
- Upon output of sampling conditions setting command.
- Upon output of sampling start command (except for sampling
busy status).
