This function inserts a synchronization command into the graphics FIFO. When the graphics processor sees this command, it allows the rest of the pipe to flush before continuing. This command is useful in certain situations, such as after a GXCopyTex command and before using a copied texture as a primitive.
This command is implemented by writing the control register that determines the format of the embedded frame buffer (EFB). Use care if placing this command within a display list.
