This sets GSP state for the LCD framebuffers, and other state as well. When the value of [[LCD]] register 0x1EF00X54 is >0x54, the GSP state for the specified screenID is immediately written to the LCD registers.

This sets GSP state for the LCD framebuffers. When the value of [[GPU/External_Registers#LCD_Source_Framebuffer_Setup|VCount]] (offset 0x54) is greater than a certain constant, the GSP state for the specified screen is immediately written to the LCD registers. This constant is 0x52 on GSP for [[11.16.0-48|11.16.0-48]], though it used to be 0x54.

 

This command should only be used when directly writing to the framebuffers; when using the GPU the framebuffer info stored in [[GSP_Shared_Memory#Framebuffer_info|GSP shared memory]] should be used instead.
