character code table is selected when n is set to 255 using the character code table selection command
ESC t n .
1) Space page top address (*1)
Page
255
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)
9 17 font (graphics)
Character data top address = FCBC80H + (character code - 80H)
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
