Decoding BT.656

Good day,

I have BT.656 video data arriving from the OMAP4's CPI port and I am trying to understand what I need to decode BT.656 traffic. Both  IPIPEIF_CFG1.INPSRC1 and INPSRC2 are set to 0.

With my current driver, I can currently get HS_VS_IRQ when using cam2_vs and cam2_hs signals. However, I plan on not using those since I am using BT.656. I would like to make the HS_VS_IRQ (or some other int) trig with BT.656.

I keep re-reading the TRM, but I can't find where exactly is the BT.656 sync extract decoder (EAV, SAV)...is it in the CPI, IPIPEIF or ISIF block ?

Many thanks,

Marc
