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[7:0]:ADC0L[7:4], if ADLJST = 1

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.
