These two bits select the clock and power-down modes (Table 4).
0 = internally controlled acquisition (6 clock cycles), 1 = externally controlled acquisition
Selects the full-scale voltage magnitude at the input (Table 3).
Selects unipolar or bipolar conversion mode (Table 3).
These are address bits for the input mux to select the “on” channel (Table 5).
