Readout Time Smaller Than or Equal to Integration Time
In this situation the RES_LENGTH register can be uploaded
with the smallest possible value, this is the value '2'. In this
case the frame rate is determined by the integration time. In
the case the readout time is equal to the integration time, the
FT_TIMER register is uploaded with a value equal to the
window size to readout plus one. In case the readout time is
smaller than the integration time the FT_TIMER register will be
uploaded with a value bigger than the window size.

Figure 16 shows this principle. While the sensor is being
readout the FRAME_VALID signal will go high to indicate the
time needed to read out the sensor.
When windowing in Y direction is desired in this mode (longer
integration time than read-out time) the following parameters
should be set: The integration time is set by the FT_TIMER
register. The actual windowing in Y is achieved when the
surrounding system discards the lines which are not desired
for the selected window.
