49 / 126 page ![]() DocID023597 Rev 11 49/126 VG6640, VD6640 Control interface 125 4.2.8 User interface set 1 registers [0x2287 to 0x23E9] Two user interface register sets are provided to allow frame-by-frame context switching of exposure, frame length, HDR merge, defect correction, PWL compression parameters and statistics accumulation. While one frame is being streamed using the active context settings, new settings may be programmed to the non-active context, ready for use by the next frame. These settings must be written with the grouped_parameter_hold flag set. The status of the integration and gain registers is reported in the frame status line. Table 17.
