2)Calculating the character data top address

The character data top address is calculated as follows:

12 24 font (graphics)

Character data top address = FCA480H + (character code - 80H) 48

9 17 font (graphics)

Character data top address = FCBC80H + (character code - 80H) 34

3)Example configuring the font data

12 24 font (in case of character code 90H on page 255) Character data top address FCA480H+(90H-80H)48 = FCA780H
