(6) Controlling Video and Graphics Image Display Positions
This module provides functions for generating the Vsync and Hsync signals for video, graphics
images, and output to the panel with desired timings with respect to the reference Vsync signal.
The positions of the video and graphics image displayed on the panel are shown in figure 27.8.
The timing of the Vsync signal for video has a restriction because the period for buffering the
input video in the large-capacity on-chip RAM should be taken into account. For details, refer to
section 27.8, Usage Notes.
