We want to know a functionality or effect for SD SAV/EAV Step Edge Control bit in SD Mode Register 1 (0x42, Bit7) of ADV7321.
Could you please explain a functionality when the bit enable or disable?
When we should use this bit? We understand, if this bit is enabled then ringing effect is suppressed.
When we enable this bit, we observed a super-black is omitted on a output signal.
We are feeding video data of between 0x01 to 0x0F to ADV7321.
After that, we can not see super-black signal on output of ADV7321 when the Step Edge Control bit is enabled. Why?
