ADV7844 Start of window for Analogue-voltage / Digital-fine Clamp Measurement?

I've got a customer asking when the measurement of both Analogue-voltage and Digital-fine clamp measurement window kicks in when CP_ANVC_POS_START[12:0] and CP_DFC_POS_START[12:0] are set default?


On the '10.2 CLAMP OPERATION' in the hardware manual it says:

'The position of the window is changed automatically (depending on PRIM_MODE[3:0] and VID_STD[5:0]) to suit the video standard in question.'

, but the customer needs exact position of the window of each supported standards.


Thanks in advance, TF
