This feature working with Column Address Re-map would produce an effect of flipping outputs SEG0-127
to SEG127-SEG0.
Address Increment Mode
If horizontal increment mode is set, the column address pointer advances after each RAM access.
If vertical increment mode is set, the row address pointer advances after each RAM access.
COM Re-map
If COM re-map is set, ROW 0-79 map to COM79-0, regardless of start and end row commands.
Set Display Start Line
This command is to set Display Start Line register to determine starting address of display RAM to be
displayed by selecting a value from 0 to 79.
Set Display Offset
This is a double byte command. The next command specifies the mapping of display start line (it is
assumed that COM0 is the display start line, display start line register equals to 0) to one of COM0-79.
For example, to move the COMX towards the COM0 direction for L lines, the 7-bit data in the second
command should be given by L. In other words, to move the COMX towards the COM79 direction for L
lines, the 7-bit data in the second command should be given by 80-L.
Set Display Mode
This command is used to set Normal Display, Entire Display On, Entire Display Off and Inverse Display.
Set Entire Display On forces the entire display to be at gray level “GS15” regardless of the contents of the
display data RAM. Set Entire Display Off forces the entire display to be at gray level “GS0” regardless of
the contents of the display data RAM. Normal Display will turn the data to ON at the corresponding gray
level. Inverse display will turn the data as follow:

Set Multiplex Ratio
This command sets multiplex ratio from 16 to 80. In POR, multiplex ratio is 80.
