NOTE: Resulting 12-bit ADC Data Word appears in the ADC Data Word Registers as follows:
ADC0H[3:0]:ADC0L[7:0], if ADLJST = 0
(ADC0H[7:4] will be sign extension of ADC0H.3 if a differential reading, otherwise = 0000b)
ADC0H[7:0]:ADC0L[7:4], if ADLJST = 1
(ADC0L[3:0] = 0000b)

AIN0 – AGND (Volts)
REF x (4095/4096)
REF x (2047/4096)
For ADLJST = 1: Upper 8-bits of the 12-bit ADC Data Word.
For ADLJST = 0: Bits7–4 are the sign extension of Bit3. Bits 3–0 are the upper 4-bits of the
12-bit ADC Data Word.
For ADLJST = 1: Bits7–4 are the lower 4-bits of the 12-bit ADC Data Word. Bits3–0 will
always read 0.
For ADLJST = 0: Bits7–0 are the lower 8-bits of the 12-bit ADC Data Word.
