ADRAM (Additional data RAM)
ADRAM is RAM that is used to store the ADATA display data. ADRAM has a capacity of 13
×
5 bits, and the stored
display data is displayed directly without the use of CGROM or CGRAM. The table below lists the correspondence
between the 4-bit ADRAM address loaded into AC and the display position on the LCD panel.

CGROM (Character generator ROM)
CGROM is ROM that is used to generate the 240 kinds of 5

×
9 dot matrix character patterns from the
8-bit character codes. CGROM has a capacity of 240

45 bits. When a character code is written to DCRAM, the
character pattern stored in CGROM corresponding to the character code is displayed at the position on the LCD
corresponding to the DCRAM address loaded into AC.
CGRAM (Character generator RAM)
CGRAM is RAM to which user programs can freely write arbitrary character patterns. Up to 16 kinds of 5
