25 / 61 page ![]() S1D2502B01 VIDEO AMP MERGED OSD PROCESSOR FOR MONITORS 24 Preliminary Row Attribute Registers (Row00 — 14, Column30) RB, RG, RR (Bit 8 — 6) Raster color is determined by these bits The raster color is chosen from out of 16 colors using these 3 bits and the row attribute register's 'RINT' bit. If 'BOXE' Bit is not '1', the setting of these three bits have no meaning. Refer to 'BOXE' bit shown below. SHA Character shadowing Character shadowing feature is carried out if you set this bit to '1'. BORD Character bordering Character bordering feature is carried out if you set this bit to '1'. BOXE (Bit B) BOX enable If you set this bit to '1', it uses the character & attribute register's 'BINV', 'BOX1', and 'BOX0' bits to carry out box drawing, and if you set it to '0', the character & attribute register's bits F~D (BINV, BOX1, BOX0) act as each raster color's B, G, and R. This has higher priority than selection by setting RB, RG, and RR bits. In other words, if the BOXE bit is set to '0', the character & attribute register's BINV, BOX1, and BOX0 each do the function of RB, RG, and RR to decide the raster color, and the original row attribute register's RB, RG, and RR don't do anything. CBli (Bit C) Color blink enable If this bit is '1', the color blinking effect is applied. Color blinking is instead of normal blinking, 8 colors appear in order in the font's character part. Its time and duty is controlled by 'BliT', 'Bli1', and 'Bli0', like in character blinking. INTE (Bit D) Intensity enable Refer to the table on the combination of BLINK/FINT, INTE, RINT, and CINT bits in the explanation of the character & attribute register's BLINK/ FINT bit. BREN (Bit E) Back raster enable If the BREN bit is '1' and the raster color is black, the raster is transparent. That is, the video back raster is shown. If not, the OSD raster covers the video's back raster. Refer to other color effect. Bit F Reserved Table 11. Register Description (Continued) Registers Bits Description |
