Sets the new conversion speed (if required)
and performs an offset correction conversion
with the internal ADC inputs shorted to REF-.
The result is stored in the null register.
(This step also selects the speed/resolution
for the ADC.)
Performs a gain-calibration conversion with
the null register contents as the starting value.
The result is stored in the calibration register.
Performs an offset-null conversion with the
internal ADC inputs shorted to the selected
input channel's negative input (IN1- or IN2-).
The next operation performs the first signal
conversion with the new setup.

Channel 1 connected to ADC inputs. Conversion begins when CS returns high.
Channel 2 connected to ADC inputs. Conversion begins when CS returns high.
IN1- connected to the ADC inputs; offset-null mode selected. Autonull conversion
begins when CS returns high, and the results are stored in the null register.
IN2- connected to the ADC inputs; offset-null mode selected. Autonull conversion
begins when CS returns high, and the results are stored in the null register.
REF- connected to the ADC inputs; offset-null mode selected. Autonull conversion
begins when CS returns high, and the results are stored in the null register.
REF+ and REF- connected to the ADC inputs; gain-calibration mode
selected. Autocal conversion begins when CS returns high, and the results are
stored in the 16-bit I/O register.
Input control word is not transferred to the control register. ADC
configuration remains unchanged and no new conversion starts when CS
returns high.
