9. Display All-Lit ON/OFF
Display all-lit ON makes the display be entirely lit. All common outputs become selectable status. Segment output
is compelled to be all-lit output. The display RAM’s data, however does not change.
Through Display all-lit OFF, the screen returns to normal display operation.
When inputting the Display OFF command in the display all-lit ON status, it changes to Power save mode (Refer
to the Power save command).
10. Read Modify Write
The read modify write command is valid when partly altering or rewriting the display data RAM, for example the
cursor indication, the blinking indication, etc. After inputting the Read modify write command, column address of
the display data RAM is incremented only when inputting the display data write command. In Read data
command, it is possible to rewrite the display data of the column address which is read, without increment of the
column address. Furthermore, when reading and writing of the display data is successively executed, the
successive address of the display data RAM is rewritten within the same page. A dummy read is needed when
reading the display data.
Read modify write command is valid until the End command is input. When inputting the End command, the
column address returns to the address before the Read modify command was input.
During the Read modify write command operation, all commands are usable except the Column address set
command.
11. End Command
This command cancels Read modify write. The column address of the display data returns to the address prior to
execution of the Read Modify Write command.
