In case non-destructive readout is used, the pulses on the
input pins still need to be given. By setting the NDR bit to "1"
the internal pixel reset pulses are suppressed but the external
pulses are still needed to have the correct timing of the frame
transfer.

Readout Timing
The sensor is readout row by row. The LINE_VALID signal
shows when valid data of a row is at the outputs.
FRAME_VALID shows which LINE_VALIDs are valid.
LINE_VALIDs when FRAME_VALID is low, must be discarded.
Figure 19 and Figure 20 illustrate this.
Note: The FRAME_VALID signal will automically go low after
480 LINE_VALID pulses in mastermode
