Frame Trigger Wait
The “Frame Trigger Wait” signal is pulled low at the start of the exposure and is pulled high when the last frame of
data is read out. The trigger signal inputted by the user should be in the valid period of the signal. If the user inputs a trigger
signal when the signal is low, the trigger signal input at this time will be ignored. The following example is the case when
Burst Count = 2, as shown in Figure 11
