VIU FID-input purpose

I wonder what's the purpose of FID input. RM and datasheet list it, but there's no description, except


• FID must change state 3 Hsync pulses into Vsync.


I don't understand ^^ it. Is there some timing diagram with specified time delays? Is FID signal required and limits sensor choice?



Also I wonder when


FIELD_IRQ and VSTART_IRQ interrupts are supposed to happen. I can't find information in RM.
