∗3 _{VL setting is the VVL voltage of the vertical clock waveform, or the same voltage as the VL power supply}
for the V driver should be used.
∗4 _{Substrate voltage (VSUB2) setting value indication}
The substrate voltage (VSUB) for modes without line addition is generated internally.
The substrate voltage setting value for use with vertical 2-line addition is indicated by a code on the
bottom surface of the image sensor. Adjust the substrate voltage to the indicated voltage.
