I'm looking at ADV7280M_Cust-VER.4.1.txt and there are writes to bit 7 of register 0x0E:
:AUTODETECT CVBS Single Ended In Ain 3, MIPI Out:
delay 10 ;
42 0F 00 ; Exit Power Down Mode
42 00 02 ; INSEL = CVBS in on Ain 3
42 0E 80 ; ADI Required Write
Is there an explanation of what this write is for? The ADV7280/ADV7281/ADV7282/ADV7283 Hardware Reference Manual shows bit 7 is reserved. Can you please explain the purpose of this bit?
