1. Bits MVC0 — MVC4 control 32 step volume control for MONO input

2. Bits LVC0 — LVC4 control 32 step volume control for LEFT input

3. Bits RVC0 — RVC4 control 32 step volume control for RIGHT input

4. Bits MC0 — MC2 control 8 distinct modes

5. Bits N3D3, N3D2, N3D1, N3D0 control programmable 3D function

6. N3D0 turns the 3D function ON (N3D0 = 1) or OFF (N3D0 = 0), and N3D1 = 0 provides a “wider” aural effect or N3D1=1a “narrower” aural effect

7. Bit OCL selects between SE with output capacitor (OCL = 0) or SE without output capacitors (OCL = 1). Default is OCL = 0

8. N3D1 selects between two different 3D configurations
