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
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
