COMMAND DESCRIPTIONS
8.1
Set Display On/Off
This command turns the display on/off, by the value of the LSB.
8.2
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.
8.3
Set Page Address
This command positions the page address to 0 to 8 possible positions in GDDRAM. Refer to
Figure 5.
8.4
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).
8.5
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).
8.6
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.
8.7
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.
8.8
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.
8.9
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.
8.10 Set LCD Bias
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.
