44<H2>Description</H2>
45<P>This function is used to set a specified hardware texture map ID as preloaded and to bind the texture to a given region of texture memory (TMEM). Unlike the GX library, which uses texture objects, GD functions set the hardware registers directly.</P>
46<P>A specified texture map can either be cached or preloaded. A cached texture resides in main memory and uses TMEM as a cache. A preloaded texture resides entirely in TMEM. This function sets the texture map to preload, while <a href="GDSetTexCached.html"><code>GDSetTexCached</code></a> function sets the texture map to cache. In either case, the texture must be bound to a particular region of TMEM.</P>
47<P>TMEM is divided into low order and high order banks. The texture may be split between the banks depending upon the texture format. For the rules governing this, refer to <a href="../gx/Texture/GXInitTexPreLoadRegion.html#TMEM_rules"><code>GXInitTexPreLoadRegion</code></a> function.</P>
