Readout Time Larger Than Integration Time
In case the readout time is larger than then integration time,
the RES_LENGTH register needs to be uploaded with a value
larger than two to compensate for the larger readout time. The
Integration Timing in Slave Mode
In slave mode the registers RES_LENGTH, DS_TIMER,
TS_TIMER and FT_TIMER are ignored. The integration timing
is now controlled by the pins INT_TIME_1, INT_TIME_2 and
INT_TIME_3, which are now active low input pins.
The relationship between the input pins and the integration
timing is illustrated in 18. The pixel is reset as soon as
IN_TIME_1 is low (active) and INT_TIME_2 and INT_TIME_3

are high. The integration starts when INT_TIME_1 becomes
high again and during this integration additional (lower) reset
can be given by activating INT_TIME_2 and INT_TIME_3
separately. At the end of the desired integration time the frame
transfer starts by making all 3 INT_TIME pins active low
simultaneously. There is always a small delay between the
applied external signals and the actual internally generated
pulses. These delays are also shown in Figure 18
