Display Data RAM (DDRAM)
This RAM stores the 8-bit character codes (see Table 2).
The DDRAM addresses correspond to the display positions (digits) of the LCD as shown below. The DDRAM
addresses (to be set in the ADC) are represented in hexadecimal.

Display position
DD RAM address (hexadecimal)
In the 1-line display mode, the ML9041A can display up to 20 characters from digit 1 to digit 20. While the
DDRAM has addresses “00” to “4F” for up to 80 character codes, the area not used for display can be used as a
RAM area for general data. When the display is shifted by instruction, the relationship between the LCD
display and the DDRAM address changes as shown below:
