VV5430
Setup Code_1
Header Code = 0001
The code_1 setup register is used to select different basic operating modes:
25/33
Note: Decreasing the system clock rate proportionately increases sensor sensitivity (by increasing exposure time), but
Bit
also decreases frame frequency. System Clock must be x1 for standard CCIR or EIA framing.
