Gray Scale/Philips Video Timing
The diagrams in this section show transfer timing for pixel (YCrCb), line (horizontal) and frame (vertical) data in Gray Scale or
Philips video modes. All output values assume a maximum pin loading of 50 pF. Note that in timing diagrams for Gray Scale/Philips
video, the label CTRL indicates the VSYNC, HSYNC and FIELD pins.
