NAME
DESCRIPTION
7, 6
PD1, PD0
These two bits select the clock and power-down modes (Table 4).
5
ACQMOD
0 = internally controlled acquisition (6 clock cycles), 1 = externally controlled acquisition
4
RNG
Selects the full-scale voltage magnitude at the input (Table 3).
3
BIP
Selects unipolar or bipolar conversion mode (Table 3).
2, 1, 0
A2, A1, A0
These are address bits for the input mux to select the “on” channel (Table 5).
