39<H2>Description</H2>
40<P>This function will cause the Graphics Processor (GP) to execute graphics commands from the display <code><em><strong>list</strong></em></code> instead of from the GP <a href="../list.html#Graphics FIFO">FIFO</a>.&nbsp;When the value of <code><em><strong>nbytes</strong></em></code> (a multiple of 32) has been read, the graphics processor will resume executing commands from the graphics FIFO.</P><P>Graphics commands from a display list are prefetched into a separate 4KB FIFO. This prevents any data prefetched for the main graphics command stream from being lost during the display list call.&nbsp;<BR><BR><B>Note:</B> A display list cannot call another display list.</P>
41<P>The display list must be padded to a length of 32 bytes.&nbsp;All the data in the display list is interpreted by the graphics processor, so any unused memory at the end of a display list should be set to <code>GX_NOP(0x00)</code>.&nbsp;If you create the display list using <code><a href="GXBeginDisplayList.html">GXBeginDisplayList</a>/<a href="GXEndDisplayList.html">GXEndDisplayList</a></code>, this padding will be done automatically.</P>
