Characters
Up to 252 kinds of 16 × 32 dot character fonts (4 characters including 1 test character are not programmable)
Each font can be divided into two parts and used as two fonts (Ex. 16 × 16 dot character font × 2)
At least 111 characters need to be divide between a 16 × 17 dot and 8 × 9 dot character font to display the caption
fonts.
