Examples
The GPO control generation is based on the internal line
count and pixel count shown in Figures 16, 17 Two pro-
grammable registers (Vertical Start and Vertical Duration)
control the vertical component of the control signal. This es-
tablishes at what line and for how many lines the control sig-
