32.1.6 Result Formatting

The 12-bit ADC conversion result can be supplied in two formats, left justified or right justified. The FRM bit controls the output format.

The figure below shows the two output formats.

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