A0, A1 - Logic Outputs (Analog), Pin 5, 6.

The logic states of A0-A1 mimic the states of the D22-D23 bits of the configuration register.

Logic Output 0 = VA-, and Logic Output 1 = VA+.

D0, D1, D2, D3 - Logic Outputs (Digital), Pin 7, 16, 17, 18.

The logic states of D0-D3 mimic the states of the D18-D21 bits of the configuration register.

Logic Output 0 = DGND, and Logic Output 1 = VD+.
