GMS 84512 / 84524
3.8.9 Character ROM
The character ROM of GMS84512/84524 stores 128 kinds of font dot pattern data.
36bytes of dot pattern data needs to display one character.
Fig 3.8.7 is a example of character dot pattern, TABLE 3.8.4 is a relation about character code
and character dot pattern address.
