34.3.5 Compare Value Registers (ADCx_CVn)
The Compare Value Registers (CV1 and CV2) contain a compare value used to compare
the conversion result when the compare function is enabled, that is, SC2[ACFE]=1. This
register is formatted in the same way as the Rn registers in different modes of operation
for both bit position definition and value format using unsigned or sign-extended 2's
complement. Therefore, the compare function uses only the CVn fields that are related to
the ADC mode of operation.
The compare value 2 register (CV2) is used only when the compare range function is
enabled, that is, SC2[ACREN]=1.
