Font data must be stored in the proper OSD ROM address according to the following table.
(1)OSD ROM address of character font data
OSD ROM address bit AD16 AD15 AD14 AD13 AD12 AD11 AD10 AD9 AD8 AD7 AD6 AD5 AD4 AD3 AD2 AD1 AD0
Line number / Character

Line number = 02 16 to 1516
Character code = 00 16 to 13F16
Font bit = 0 : Left font
1 : Right font
Example) The font data “60” (shaded area ) of the character code “AA 16” is stored in address
1 0 0 1 0 1 0 0 1 0 1 0 1 0 1 0 0 2 =1295416.
(2)OSD ROM address of extra font data
