This command has no write parameters.
This command is used in conjunction with the Write Input Source Select and the Write Splash Screen Select commands to start the process of retrieving a splash screen from flash for display.
The splash screen is read from flash and sent down the processing path of the controller once, to be stored in memory for display at the end of the processing path. All image processing settings (such as image crop, image orientation, display size, splash screen select, and splash screen as input source) must be set by the user before executing this command. Any data path processing changed after the splash screen has been executed requires this command to be re-executed before the result is seen on the display. Thus, the splash screen retrieval process repeats each time this command is received. See the Write Image Freeze command for more information on hiding on-screen artifacts when selecting and retrieving a splash image.
The user must review the notes for the Write Input Source Select command to understand the concept of source-associated commands. This concept determines when source-associated commands are executed by the system. This command is a source-associated command; however, this command has no maintained state or history and has no settings to be stored or reused by the system.
When this command is processed in Display - Splash Screen mode, the system automatically initializes the system color processing based on the splash header information prior to sending the splash image down the data path. However, in Light Control - Splash Pattern mode, no color processing is performed and the stored bitmap is displayed as is, irrespective of whether the image is input image in splash pattern mode. The images must be stored in RGB565 format in flash.
