¡ Semiconductor
Character Generator ROM (CG ROM)
First line
Second line
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.

• Since the MSM6222B-xx has a DD RAM capacity of up to 80 characters, up to 4
When the display is shifted by instruction, the correspondence between the LCD
display position and the DD RAM address changes as shown below:
MSM5259 devices can be connected to the MSM6222B-xx in the 2-line display mode.
