Non-destructive Readout (NDR)
The sensor can also be read out in a non-destructive way. After
a pixel is initially reset, it can be read multiple times, without
resetting. The initial reset level and all intermediate signals can
be recorded. High light levels will saturate the pixels quickly,
but a useful signal is obtained from the early samples. For low
Note
5. This mode can be activated by setting the NDR SPI register. The NDR SPI register should only be changed during FOT. The NDR bit should be set high during
the first Frame Overhead Time after the pixel array has been reset; the NDR bit should be set low during the last Frame Overhead Time before the pixel array is
being reset.

light levels, one has to use the later or latest samples.
Essentially an active pixel array is read multiple times, and
reset only once. The external system intelligence takes care
of the interpretation of the data. Table 14 summarizes the
advantages and disadvantages of non-destructive readout
