NOTE: Resulting 10-bit ADC Data Word appears in the ADC Data Word Registers as follows:
ADC0H[1:0]:ADC0L[7:0], if ADLJST = 0
ADC0H[7:0]:ADC0L[7:6], if ADLJST = 1

For ADLJST = 1: Upper 8-bits of the 10-bit ADC Data Word.
For ADLJST = 0: Bits7-2 are the sign extension of Bit1. Bits 1-0 are the upper 2-bits of the
10-bit ADC Data Word.
For ADLJST = 1: Bits7-6 are the lower 2-bits of the 10-bit ADC Data Word. Bits5-0 will
always read 0.
For ADLJST = 0: Bits7-0 are the lower 8-bits of the 10-bit ADC Data Word.
(ADC0H[7:2] will be sign extension of ADC0H.1 if a differential reading, otherwise = 000000b)
