The meaning of the 12 data bits depends on the selected register. For the DAC register, bits D11...D4 determine
the new DAC output value:

If the control register is selected, then D1, D0 of the 12 data bits are used to program the reference voltage:

NOTE: A 0.1
F bypass capacitor must be installed on
the reference pin (pin 6). If internal reference is used a
10
F capacitor must also be installed for reference
voltage stability.
CAUTION:
If external reference voltage is applied to the REF pin, external reference MUST be selected.
