10-bit ADC Mode
In 10-bit mode, the ADC produces 12-bit output but the output data in AFEC_CDR is shifted 2 bits to the right,
removing the two LSBs of the 12-bit ADC.
removing the two LSBs of the 12-bit ADC.
The gain and offset have the same values as for 12-bit mode, with digital full-scale output code range reduced to
1024 (vs 4096).
