7.4.2.2 Test Mode 1 - Horizontal Gradient

This mode provides LVDS data that progresses horizontally from dark to light output values. This mode is highly variable, allowing control over the starting value of the gradient, the width of the gradient, and the increment rate of the gradient. The starting value can be set in the Test Pattern Value register, the width (in number of pixels) of each gradient step is set via Test Pattern Pitch register, and increment rate (in LSBs) is set via the Test Pattern Step register. When the LVDS Horizontal Gradient test pattern is selected, the ramp begins immediately and counts to the maximum value, and then repeats throughout the entire Valid Pixel region.
