display start line.
The data of Y address is displayed on the display start line depending on the value of the shift
command register and the display start line register.
It is possible to write in DDRAM by 16-bits access with the data of 16 bits data bus D
16 bits data access mode is possible by setting the value of WLS register to “1”.
The data of this register are preset to the display line counter per FLM signal transition.
Line counter is counted up in synchronization with CL input and generates line address that read
This IC includes display memory
In gray mode, neighboring 4-bit data are displayed by segment driver with 16 grays, respectively.
3 outputs of segment driver compose 1 pixel of RGB and 128 162 pixels are displayed with 4096
Address area of X direction is varied according to accessed data length. The area of X direction
Each command should be set to 8-bits(D
16-bit access is available at display RAM access.
When displaying the DDRAM data, it is the contents of Y address register that is corresponding to
