Command Description
Set Display On/Off
This command alternatively turns the display on and off. When display
off is issued with entire display on, power save mode will be entered. See
“Set Power Save Mode” for details.
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 8-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.
Set Lower Column Address
This command specifies the lower nibble of the 8-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.
Set Segment Re-map
This commands changes the mapping between the display data col-
umn 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 nor-
mal display, a RAM data of 1 indicates an “ON” pixel while in reverse dis-
play, a RAM data of 0 indicates an “ON” pixel. In icon mode, the icon line
is not reversed 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. This command will be used with
“Set Display Display ON/OFF” command to form a compound command
for entering power save mode. See “Set Power Save Mode”.
Set LCD Bias
This command selects a suitable bias ratio (1/6 or 1/8) required for
driving the particular LCD panel in use. The POR default for SSD1812 is
set to 1/8 bias. For setting 1/4, 1/5, 1/7 and 1/9 bias, an extended com-
pound command should be used.
Set Read-Modify-Write Mode
This command puts the chip in read-modify-write mode in which:
1. the column address is saved before entering the mode
2. the column address is incremented by display data write but not by
display data read
Set End of Read-Modify-Write Mode
This command relieves the chip from read-modify-write mode. The
column address that is saved before entering read-modify-write mode
will be restored.
Software Reset
This command causes some of the internal status of the chip to be
initialized:
1. Display is OFF
3. Normal segment and display data column address mapping
(SEG0 mapped to address 00H)
4. Read-modify-write mode is OFF
5. Power control register is set at 0
6. Bias ratio is set at 1/8
7. Static indicator is OFF
8. Display start line is set at display RAM address 0
9. Column address counter is set at 0
10. Page address is set at 0
11. Normal scan direction of the COM outputs
12. Internal Regulator Resistor Ratio at 4
13. Contrast control register is set at 20H
14. Test mode is OFF
Set COM Output Scan Direction
This command sets the scan direction of the COM output allowing
layout flexibility in LCD module assembly.
Set Power Control Register
This command turns on/off the various power circuits associated
with the chip.
Set Internal Regulator Resistors Ratio
This command is to enable any one of the eight internal resistor
sets for different regulator gain when using internal regulator resistor
network (IRS pin pulled high). The relationship between the VL6 and
the 64 levels of contrast step is TBD.
Set Contrast Control Register
This commands adjusts the contrast of the LCD panel by changing
V
L6
of the LCD drive voltage provided by the On-Chip power circuits.
V
L6
is set with 64 steps (6-bit) contrast control register. It is a com-
