Selects the output from CVBS1(2) OUT (pin 4 (17)) for SCART connector.
Switches the frequency of bandwidth limit filters for Cb/Cr
Selects the output from Y/Cb/Cr OUT1(2) (pins 6, 8, 10 (19, 21, 23)).
Switches the bandwidth limit filter 1 (2).
Mixes Y with C for MONITOR OUT (pin 2).
Selects the output from MONITOR OUT (pin 2).
Switches the f0 of the bandwidth limit filter for YCbCr(RGB)
Note: This function is not valid for the filter for CVBS. For the CVBS filter, this data is
Switches the f0 of the bandwidth limit filter for YCbCr(RGB) and CVBS
Note: While HD, VD or FB-out is output, according as the f0 is set to lower, the

Refer also to Function Descriptions.
The cutoff frequency of bandwidth limit filters for Cb/Cr is 1/2 to Y.
When YC MIX = 1, a mixed signal is output.
