Control
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)
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
