(4) 16 bit data access to DDRAM
It is possible to write in DDRAM by 16-bits access with the data of 16 bits data bus D
0
~D

.
16 bits data access mode is possible by setting the value of WLS register to “1”.

) as well as to 16-bit access mode.
16-bit access is available at display RAM access.
(5) Display start line register
When displaying the DDRAM data, it is the contents of Y address register that is corresponding to
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.
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
out 384bit data from DDRAM to LCD driver circuit.
(6) DDRAM addressing
This IC includes display memory Bit mapped that is composed of 1,536 bit of X direction
(12bit

128) and 162bit of Y direction.
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
