Font data must be stored in the proper OSD ROM address according to the following table.

Character code “AA16”
Notes 1 : The 80-byte addresses corresponding to the character code “7F16” and “8016” in OSD ROM are the test
data storning area. Set “FF16” to the area (We stores the test data to this area and the different data
from “FF16” is stored for the actual products.)
The test data storing area :
addresses 1100016 + (4 + 2n) ! 10016 + FE16 to 1100016 + (5 + 2n) ! 10016 + 0116 (n = 0 to 19)
addresses 114FE16 to 1150116
addresses 116FE16 to 1170116

addresses 138FE16 to 1390116
addresses 13AFE16 to 13B0116
2 : The character code “0916” is used for “transparent space” when displaying Closed Caption.
Therefore, set “0016” to the 40-byte addresses corresponding to the character code “0916.”
The transparent space font data storing area :
addresses 1100016 + (4 + 2n) ! 10016 + 1216 to 1100016 + (4 + 2n) ! 10016 + 1316 (n = 0 to 19)

addresses 1161216 and 1161316
