Regardless of the contents of the display data RAM, the LCD screen is compelled to be all-off (including
the icon display).

2. Display Start Line
The line address of the display data RAM indicating the display start line is set. The display start line corresponds to
COM1. The display area read from the display data RAM corresponds to the number of the lines set by the Duty

Changing the display start line using this command allows for page change on the display screen as well as vertical
smooth scroll.
3. Page Address Set
The page address is set when accessing the display data RAM from the MPU. It is possible to access the display
data RAM from the MPU with the page address and the column address commands. Even if the page address is
changed, there is no change in the display screen during operation. Page 8 is assigned to the icon display. D0 only
is valid.
