Figure 3-16: ExSync, Programmable Mode - Exposure Start when Frame Valid is High, Exposure
Stop when Frame Valid is Low
If the exposure starts when Frame Valid is high and ends while Frame Valid is low (see Table for
values n to z):
• The actual start of exposure can be x µs later than the rise of the ExSync signal.
• Actual length of exposure time = n - y µs ... n + z µs
