Clamp and DC-restore circuit control (06H: D7-D2)
Each CVBS and Y input has the sync tip clamp circuit. The DC-restore circuit has two clamp voltages 0.7V(typ) and
2.2V(typ) to support both RGB and YPbPr signal. They correspond to 0.35V(typ) and 1.1V(typ) at the SCART connector
when matched by 75ohm resistors. The CLAMP1, CLAMP0 and CLAMPB bits select the input circuit for ENCRC pin
(Encoder Red/Chroma), ENCB pin (Encoder Blue), VCRRC pin (VCR Red/Chroma) and VCRB pin (VCR Blue)
respectively. VCLP1-0 bits select the sync source of DC- restore circuit.

Note: When the VTV2-0 bits = “001”(source for TV = Encoder CVBS /RGB), TVG bit = “1” (TVG
= active) and VCLP1-0 bits = “11”(DC restore source = ENCG), the sync tip is selected even
if the CLAMP2 bit = “0”.
