The Analog/Digital Converter
Conversion Result
The result of a conversion is stored in the result register ADC_DAT, or in register
ADC_DAT2 for an injected conversion.
The position of the result depends on the basic operating mode (compatibility or
enhanced) and on the selected resolution (8-bit or 10-bit).
Note: Bitfield CHNR of register ADC_DAT is loaded by the ADC to indicate, which
channel the result refers to. Bitfield CHNR of register ADC_DAT2 is loaded by the
CPU to select the analog channel, which is to be injected.

A/D Conversion Result
The digital result of the most recent conversion.
In compatibility mode, the result is placed as follows:
8-bit: ADRES[9:2]
10-bit: ADRES[9:0]
In enhanced mode, the result is placed as follows:
8-bit: ADRES[11:4]
10-bit: ADRES[11:2]
Note: Unused bits of ADRES are always set to 0.
