OPT8241-CDK-EVM: OPT9221 Register Description

Part Number: OPT8241-CDK-EVM

In the Voxel Viewer application there are several parameters that indicate they are OPT9221 registers but are not described in the datasheet and don't have a description provided in the application.  These include: data_latency, illum_ovtemp_thresh, init_2, init_3, init_4, init_5, sensor_ovtemp_thresh, sscg_en, sscg_modulation, sscg_period.  Can TI provide a description or do we just consider these to be magic register values?
