This commands converts the specified addresses to physical addresses, then writes these addresses and the specified parameters to the [[GPU]] registers at 0x1EF00010 and 0x1EF00020. The associated buffer address must not be <= to the main buffer address, thus the associated buffer address must not be zero as well. When the bufX address is zero, processing for the bufX parameters is skipped. | This commands converts the specified addresses to physical addresses, then writes these addresses and the specified parameters to the [[GPU]] registers at 0x1EF00010 and 0x1EF00020.
