Case 2 - Exposure Start With Frame Valid Low
Figure 3-7: ExSync, Programmable Mode - Exposure Start with Frame Valid Low
If the ExSync signal falls while frame valid is low as shown in Figure 3-7:
• Exposure will start after a delay of 3.7 µs.
• The actual length of the exposure time will be equal to the programmed time plus 94.5 µs.

As shown in Figure 3-7, FVAL must be low for at least 1 µs before the ExSync signal
rises.
