Note: Writing any value to this register performs a register reset, which causes all registers to revert to their default values (except  
74h, which forces the serial configuration). Reading this register returns the ID code of the part and a code for the type of 3D Stereo  
Enhancement.  
ID[9:0] Identify Capability. The ID decodes the capabilities of AD1885 based on the following:
