Table 15. RF video output
Note: 18: When input the video signal via ENCRC pin or VCRRC pin, set CLAMP1-0 bits respectively.
Note: 19 When VTV2-0 bit =“001”, TVG bit =“1” and VRF1-0 bit =“01”, RFV pin output is same
as TVG pin output (Encoder G).
■ Video Output Control (05H: D6-D0)
Each video outputs can be set to Hi-Z individually via control registers. These setting are ignored when the AUTO bit =
“1”. When the CIO bit = “1”, the VCRC pin outputs 0V even if the VCRC bit = “0”. When the CIO bit = “0”, the VCRC
pin follows the setting of VCRC bit. Please refer to the “Red/Chroma Bi-directional Control for VCR SCART”.
