Note: Operation in the X and Y directions can be performed independently.
The internal timing circuit starts operating at the fall timing of the clock pulse immediately after the start pulse goes "Low".
It doesn’t matter how many times the clock pulse goes “Low” during the "Low" period of the start pulse.
The integration time is determined by the start pulse cycles. However, scince the charge storage of each pixel is carried out
between the signal readout of that pixel and the next signal readout of the same pixel, the start time of charge integration differs
depending on each pixel. In addition, the next start pulse cannot be input until signal readout from all pixels is completed.
The above timing chart applies to operation at 5 MHz. If operated at 10 MHz, the DO, Trig and EOC timings may delay by half a
clock cycle.
