Vertical Position Register
The Vertical Position Register (Table 6) sets the vertical placement of the OSD on
the screen. The unit of measure for placement is the number of scan lines from
the top of the TV field.
Table 9
The value required for this register can be computed using the following equation:
VERT_POS represents the contents of bits 5,4,3,2,1,0 of the Vertical Position
Register (VERT_POS). The default value is 0. When the value is 0, the OSD is at
the top-most OSD position on the screen, with an offset of 06h scan lines above
the OSD area.
VERT_POS is the number of scan lines from the V
