Setup Code_2
Header Code = 0010
Valid data bits: 12
The code_2 setup register is used to select read data, valid pixels and video output operating modes:
The table below shows the function of SEL0 and SEL1 (Bit 2 and Bit 3); the default value of SEL0 is set by the CPE pin level:
Coarse and Fine Exposure Values.
