(Example 1)
bits represent the character code of the character. In internal CG ROM, character codes 00H to 7FH
represent the predefined “internal” CG ROM characters, and codes 80H to FFH represent the user’s
own “external” characters. In external CG ROM mode, all 256 codes from 00H to FFH can be used to
represent the user’s own characters. The three least significant bits indicate one of the eight rows of
eight dots that define the character’s shape.
