Linux: replacement of ambient data in Voxel SDK

Tool/software: Linux


From the document on OPT9221, I understand that phase data is 12 bits whether

it is sent by TFC (to Voxel SDK running at host application) in either 4 byte mode (Ref : 4-Byte Mode (default))  or 2 byte mode (Ref : 2-Byte Mode)..

I see that a virtual function named _getDataToReplace  is used below -

virtual bool _getDataToReplace(uint32_t &dataToReplace); // phase data replaces either ambient or phase data in 16 bit mode. This parameter defines that data

Can you explain the purpose of the above function ?

How is it used in the TinTin camera in a 2 byte mode operation ?
