The 10-bit ADC conversion result can be supplied in two formats: left-justified or right-justified. The ADC Result Format/Alignment Selection (FM) bit controls the output format as shown in Figure 1.

Important: Writes to the
ADRES register pair are always right-justified, regardless of the
selected format mode. Therefore, data read after writing to ADRES when FM =
0 will be shifted left four places.
