READ CONTROL
The readout of the analog pixel values is controlled by A rising CLK edge with a hi value at SI resets the inter-
the followoing pins:
nal read out circuit, initiating a readout of the previously
sampled pixel values. While clocking more then N
clocks the read out will restart with pixel #1 without
sampling. Thus a non-destructive re-read is possible.
