Does ADV7842 provide any register controls for the memory driving current adjustment?


Customer reports a dot noise issue for CVBS input when 3D-Comb is enabled. The issue doesn't occur on every board, the failure rate is around 35%, and for those boards with issues the memory BIST test are also failed. The memory they are using is M13S128168A -5TG2N.
