Character Generator ROM (CG ROM)
The CG ROM is used to generate 5 x 7 dots (160 kinds) or 5 x 10 dots (32 kinds) character
patterns from an 8-bit DD RAM character code signal.
The correspondence between 8-bit character codes and character patterns is shown in
Table 2.
When the 8-bit character code of the CG ROM is written to the DD RAM, the character
pattern of the CG ROM corresponding to the code is displayed on the LCD display position
corresponding to the DD RAM address.
