COMMAND DESCRIPTIONS
Set Display On/Off
This command turns the display on/off, by the value of the LSB.
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 63. With value equals to 0, D0 of Page 0 is
mapped to COM0. With value equals to 1, D1 of Page0 is mapped to COM0. The display start
line values of 0 to 63 are assigned to Page 0 to 7.
Set Page Address
This command positions the page address to 0 to 8 possible positions in GDDRAM. Refer to
Figure 5.
Set Higher Column Address
This command specifies the higher nibble of the 7-bit column address of the display data RAM.
The column address will be incremented by each data access after it is pre-set by the MCU and
returning to 0 once overflow (>95).
Set Lower Column Address
This command specifies the lower nibble of the 7-bit column address of the display data RAM.
The column address will be incremented by each data access after it is pre-set by the MCU and
returning to 0 once overflow (>95).
Set Temperature Coefficient (TC) Value
This command is to set 1 out of 4 different temperature coefficients in order to match various
liquid crystal temperature grades.
Set Segment Re-map
This commands changes the mapping between the display data column address and segment
driver. It allows flexibility in layout during LCD module assembly. Refer to Figure 5.
Set Normal/Reverse Display
This command sets the display to be either normal/reverse. In normal display, a RAM data of 1
indicates an “ON” pixel while in reverse display; a RAM data of 0 indicates an “ON” pixel. The
icon line is not affected by this command.
Set Entire Display On/Off
This command forces the entire display, including the icon row, to be “ON” regardless of the
contents of the display data RAM. This command has priority over normal/reverse display.
To execute this command, Set Display On command must be sent in advance.
This command selects a suitable bias ratio (1/4 to 1/9) required for driving the particular LCD
panel in use. The POR is set to 1/9 bias.
