Character code = 00 16 to FF16 (Do not set 7F16 and 8016.)
Font bit = 0: Left font

Notes 1 : The 80-byte addresses corresponding to the character code “7F 16” and “8016” in OSD ROM are the test
data storning area. Set “FF 16” 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 1000 16 + (4 + 2n) ! 10016 + FE16 to 100016 + (5 + 2n) ! 10016 + 0116 (n = 0 to 19)
addresses 14FE 16 to 150116
addresses 16FE 16 to 170116

addresses 38FE 16 to 390116
addresses 3AFE16 to 3B0116
2 : The character code “09 16” is used for “transparent space” when displaying Closed Caption.
Therefore, set “00 16” to the 40-byte addresses corresponding to the character code “09 16.”
The transparent space font data storing area :
addresses 1000 16 + (4 + 2n) ! 10016 + 1216 to 100016 + (4 + 2n) ! 10016 + 1316 (n = 0 to 19)

addresses 1612 16 and 161316
