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.

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.)
