SOLOMON

9.13 Set PWM and FRC

This command is used to select the number of frames used in frame rate control, and the

number of levels in the pulse width modulation.

9.14 Set Segment Re-map

This command changes the mapping between the display data column address and

segment driver. It allows flexibility in layout during LCD module assembly. Refer to Figure 7.

9.15 Set Icon Enable

This command enable/disable the Icon display. When Icon display is enabled and page

address is set to Page 16. This is only one way to set the page address to 16. Therefore, when

writing data for the icon, ICONS control register ON instruction would be used to set the page

address to 16.

9.16 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/invert display. To

execute this command, Set Display On command must be sent in advance.

9.17 Set Normal/Inverse Display

This command sets the display to be either normal/inverse. In normal display, a RAM

data of 1 indicates an “ON” pixel. While in invert display, a RAM data of 0 indicates an “ON”

pixel. The icon line is not affected by this command.

9.18 Set Power Save Mode

This command is used to force the chip to enter Sleep Mode.

9.19 Start Internal Oscillator

After POR, the internal oscillator is OFF. It should be turned ON by sending this

command to the chip.

9.20 Set Display On/Off

This command turns the display on/off, by the value of the LSB.

9.21 Set Page Address

This command positions the page address to 0 to 15 possible positions in GDDRAM.

Refer to figure 7.

Set Page Address command cannot be used to set the page address to “16”. Use ICON

control register ON/OFF command to set the page address to “16”.

9.22 Set COM Output Scan Direction

This command sets the scan direction of the COM output allowing layout flexibility in LCD

module assembly.

9.23 Set Modify-Read

This command stops the automatic increment of the column address after read display

data. The column address is still automatic increment due to write display data.
