3.6.3

Border or Shadow Color

The border or shadow color is separately programmable for each separate OSD window. This value

is selected by bits WSRi, WSGi and WSBi for each of the four OSD windows. The value for each

color is shown in Table 17.

3.6.4

Bordering or Shadowing Size

The size of the bordering or shadowing width is separately programmable for each separate OSD

window. This value is selected by bits BSWWi[2:0] for each of the four OSD windows. The width

size is from 0 to 14 pixels, in steps of 2 pixels each.

Width Size = BSWWi[2:0] x 2 pixels

The size of the bordering or shadowing height is selected by bits BSHWi[3:0] for each of the four

windows. The height size is from 0 to 30 lines, in steps of 2 scan lines each.

Height Size = BSHWi[3:0] x 2 scan lines.
