9.6 Data Transfer Modes
The module has three kinds color modes for transferring data to the display RAM. These are 12-bit color per pixel, 16-bit
color per pixel and 18-bit color per pixel. The data format is described for each interface. Data can be downloaded to the
frame memory by 2 methods.
9.6.1 Method 1
The image data is sent to the frame memory in successive frame writes, each time the frame memory is filled, the frame
memory pointer is reset to the start point and the next frame is written.
9.6.2 Method 2
The image data is sent and at the end of each frame memory download, a command is sent to stop frame memory write.
Then start memory write command is sent, and a new frame is downloaded.
Note 1: These apply to all data transfer Color modes on both serial and parallel interfaces.
Note 2: The frame memory can contain both odd and even number of pixels for both methods. Only complete pixel data will be stored in
the frame memory.
