Register 14: ADC Control (ADCCTL), offset 0x038
This register configures the voltage reference. The voltage references for the conversion can be
VREFA+ and VREFA- or VDDA and GNDA. Note that values set in this register apply to all ADC
modules, it is not possible to set one module to use internal references and another to use external
references.

compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
