Minimum value for I

C-bus bit DOWND = 1.
The data is for both input and output direction.
This parameter is arbitrary, if PIXCLKI is looped through the VGC.
If an internal oscillator is used, crystal deviation of nominal frequency is directly proportional to the deviation of
subcarrier frequency and line/field frequency.
