16-bit ADC1 Data Word appears in the ADC1 Data Word Registers as follows:
Example: ADC1 Data Word Conversion Map, AIN1 Input in Single-Ended Mode
For differential mode, the differential data word appears in ADC0H and ADC0L. The single-
ended ADC1 results are always present in ADC1H and ADC1L, regardless of the operating
mode.
