• Since the MSM6222B-xx has a DD RAM capacity of up to 80 characters, up to 4

MSM5259 devices can be connected to the MSM6222B-xx in the 2-line display mode.

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.
