ADC0 Data Word High-Order Bits.
For AD0LJST = 0: Bits 7-4 are the sign extension of Bit3. Bits 3-0 are the upper 4 bits of the 12-bit
ADC0 Data Word.
For AD0LJST = 1: Bits 7-0 are the most-significant bits of the 12-bit ADC0 Data Word.
ADC0 Data Word Low-Order Bits.
For AD0LJST = 0: Bits 7-0 are the lower 8 bits of the 12-bit ADC0 Data Word.
For AD0LJST = 1: Bits 7-4 are the lower 4 bits of the 12-bit ADC0 Data Word. Bits3-0 will always
read ‘0’.
