Control
Tables 1 and 2 describe how to read the conversion results and how to configure the data converter. The default
values (were applicable) show the state after a power-on reset.

The output can be configured for 2s complement or straight binary format (see D11/control register).
The output code is given by:

The PGA gain is determined by writing to G20.
Gain (dB) = 1dB
× G20. max = 7dB. The range of G20 is 0 to 7.
