63 / 138 page ![]() 63/138 ADE3800 Register Description by Block ● If it makes the complete 8x8 grid smaller than the total display area, the 8x8 pattern repeats itself across the entire display area, both vertically and horizontally 4.11.3.1 Cell Reset When PGEN_P0_MODE[1] bit is set, the bar counters will be reset to bar 0, and gradients color counters will be reset to the default color value C0, each time a new grid cell is reached. This is to be combined with bar offset settings (refer to Section 4.11.2.2: Bar Width, Height and Offset Control and the example provided hereafter). For example, this will affect all patterns with non-zero values for PGEN_P0_GRADSTEP_X and/or PGEN_P0_GRADSTEP_Y. 4.11.3.2 Color C0 Replacement When PGEN_P0_MODE[0] bit is set, the input video signal takes the place of color C0. In that case, non-zero gradients will apply the increment value to each R G B color of the input signal, not C0. Note: If the displayed picture has noticiable jitter, the input R G B values are not stable and may generate heavy noise on screen when the gradient applied to R G B values rolls over from FF to 00. 4.11.4 Borders The border generator adds a single pixel wide borderline to the panel area. There are 4 edges: top, bottom, left and right. Each edge can be enabled independently, and programmed to one of 8 basic colors using a 3-bit RGB mask: Figure 10: 8x8 Grip Mapping Example Table 24: Borders Colors Colour Red Green Blue Value Black 0 0 0 0 Blue 0 0 1 1 Green 0 1 0 2 Cyan 0 1 1 3 Red 1 0 0 4 Magenta 1 0 1 5 Yellow 1 1 0 6 Grid 0 01234567 Grid 0 01234567 this last part of Grid 0 Grid 1 01234567 Grid 1 01234567 01234567 Grid 0 01234567 Grid 1 grid’s width and height the display area: grids repeat both DISPLAY AREA One Grid with 8 Cells 1 Cell horizontally and this bottom part of Grid 1 (all cells) is not displayed (cells 1 to 7) is not displayed are smaller than vertically |
