Both channel 0s are converted first,
followed by conversion of both channel 1s.

SBAS383–JUNE 2007
Output data consist of a channel indicator ('0' for
CHx0 or '1' for CHx1), followed by the ADC indicator
('0' for CHAx or '1' for CHBx), 12 bits of conversion
results, and ends with '00'.
In the same way as Mode II, Mode IV uses the
SDOA output line exclusively to transmit data while
the multiplexer channels are switched automatically.
Following the first conversion after M1 goes high, the
SDOB output tri-states (see
Figure 19
).
