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.
