External generator mode.
The senior five bits define the start address in external memory of the CG RAM area. The next
eight 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.
