29.3.5 Compare value registers (ADCx_CVn)
The compare value registers (CV1 and CV2) contain a compare value used to compare
with the conversion result when the compare function is enabled (ACFE=1). This register
is formatted the same for both bit position definition and value format (unsigned or sign-
extended 2's complement) as the data result registers (Rn) in the different modes of
operation. Therefore, the compare function only uses the compare value register bits that
are related to the ADC mode of operation.
The compare value 2 register (CV2) is utilized only when the compare range function is
enabled (ACREN=1).
Addresses: ADC0_CV1 is FFFF_8600h base + 18h offset = FFFF_8618h
