Notes 1 : The 80-byte addresses corresponding to the character code “7F
16
” and “80
16
” 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 “FF
16
” is stored for the actual products.)
The test data storing area :
addresses 1000
16
+ (4 + 2n) ✕ 100
16
+ FE
16
to 1000
16
+ (5 + 2n) ✕ 100
16
+ 01
16
(n = 0 to 19)
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

+ (4 + 2n) ✕ 100
