T6963CFG assign External character generator, when character code set 80H to FFH in using internal
character generator. Character code 00H to 80H assign External character generator, when 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 mode, 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 RAM 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.
