255 Space page F CA480H FCBC80H
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
Character data top address FCA480H+(90H-80H) × 48=FCA780H
