Figure 5.18. ADC1 Data Word Example

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

(AMX1SL = 0x00)

; ‘n’ = 16

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.
