Free-running
In this mode, a rising edge of internal trigger the start of integration and readout.
The integration time is defined by a
Exposure Time Command
. The sensor
autonomously integrates during this predefined time, after which the
Acquisition
starts and the image array is readout sequentially. A falling edge on the
synchronization pin does not have any impact on the readout or integration and
subsequent frames are started again for each rising edge. Figure 8 shows the
relation between the internal trigger signal and the exposure/readout timing. The
WAIT is optional.
