R61509V Target Spec
Rev. 0.11 April 25, 2008, page 136 of 181
8-Color Display Mode
The R61509V has a function to display in eight colors. In this display mode, only V0 and V63 are used
and power supplies to other grayscales (V1 to V62) are turned off to reduce power consumption.
In 8-color display mode, the γ-adjustment registers R300 to R309 are disabled and the power supplies to V1
to V62 are halted. The R61509V does not require GRAM data rewrite for 8-color display by writing the
MSB to the rest in each dot data to display in 8 colors.
