24 / 61 page  VIDEO AMP MERGED OSD PROCESSOR FOR MONITORS S1D2502B01 23 Preliminary Row Attribute Registers (Row00— 14, Column30) VZ1, VZ0 (Bit 1, 0) Vertical character size control As shown above, the vertical character size is decided by using these two bits in combination. HZ1, HZ0 (Bit 3, 2) Horizontal character size control As shown above, the horizontal character size is decided by using these two bits in combination. However, unlike VZ, the surrounding area (row) is taken over in the amount of the HZ increase, so you must keep that in mind when changing font size. Refer to Character Size. CINT (Bit 4) Character color intensity When this bit is set to '1', the color intensity of the character on the same row becomes high. Refer to BLINK/FINT, INTE, RINT, and CINT's combination chart in the previous page. (Even if you change this bit, you can't check the intensity feature on the demo board. This is because the OSD IC's output INT is applied as the video Pre Amp's input, and the demo board doesn't apply the OSD IC's INT output to the Pre Amp.) RINT (Bit 5) Raster color intensity When this bit is set to '1', the color intensity of the raster on the same row becomes high. Refer to BLINK/FINT, INTE, RINT, and CINT's combination chart in the previous page. (Like CINT given above, you can't check RINT's feature on the demo board.) Table 11.
