30 / 61 page ![]() VIDEO AMP MERGED OSD PROCESSOR FOR MONITORS S1D2502B01 29 Preliminary Tabel 4. Register Description (Continued) Registers Bits Description Frame Control Registers — 2 (Row 15, Column 02) VP7 — VP0 Vertical start position control ( = VP[7:0] × 4) Signifies top margin height from the V-Sync reference edge. HP7 — HP0 Horizontal start position control ( = HP[7:0] × 6) Signifies delay of the horizontal display from the H-Sync reference edge to the character's 1st pixel location. V-AMP Control Registers — 0 (Row 15, Column 03) VC7 — VC0 (bit7 — 0) The contrast adjustment is made by contrdling simultaneously the gain of three internal variable gain amplifiers. The contrast adjustment allows to cover a typical range of 38dB. V-AMP Control Registers — 1 (Row 15, Column 04) BRT7 — BRT0 (bit7 — 0) The brightness adjustment controls to add the same black level (pedestal) to the 3-channel R/G/B signals after contrast amplifier. V-AMP Control Registers — 2 (Row 15, Column 05) RSB7 — RSB0 (bit7 — 0) R channel SUB contrast control. The SUB contrast adjustment is used to adjust the white balance, and the gain of each channel is controlled. The SUB contrast adjustment allows you to cover a typical tange of 12dB. V-AMP Control Registers - 3 (Row 15, Column 06) GSB7 — GSB0 (bit7 — 0) G channel SUB contrast control. The SUB contrast adjustment is used to adjust the white balance, and the gain of each channel is controlled. The SUB contrast adjustment allows you to cover a typical tange of 12dB. V-AMP Control Registers - 4 (Row 15, Column 07) BSB7 — BSB0 (bit7 — 0) B channel SUB contrast control. The SUB contrast adjustment is used to adjust the white balance, and the gain of each channel is controlled. The SUB contrast adjustment allows you to cover a typical tange of 12dB. V-AMP Control Registers - 5 (Row 15, Column 08) OSD7 — OSD0 (bit7 — 0) The OSD contrast adjustment is made by contrdling simultaneously the gain of three internal variable gain amplifiers. The OSD contrast adjustment allows to cover a typical range of 38dB. V-AMP Control Registers - 6 (Row 15, Column 09) RWB7 — RWB0 (bit7 — 0) R channel cut-off control. The cut-off adjustment is used to adjust the raster white balance. V-AMP Control Registers - 7 (Row 15, Column 10) GWB7 — GWB0 (bit7 — 0) G channel cut-off control. The cut-off adjustment is used to adjust the raster white balance. |
