Table 20-9.
• Bits 2 - Reserved
This bit is unused and reserved for future use. For compatibility reasons always write this bit to
zero when this register is written.
• Bits 1:0 - MUXNEG[1:0]: MUX selection on Negative ADC input
These bits define the MUX selection for the negative ADC input when differential measurements
are done. For internal or single-ended measurements, these bits are not in use.
