33<P>Cancels the effect of the <a href="ICFreeze.html"><code>ICFreeze</code></a> function. Old instruction cache blocks will now be invalidated on subsequent L1 instruction misses.</P>
34<P>In PowerPC architecture jargon, this feature is referred to as unlocking the instruction cache.&nbsp;In Revolution, freeze is used to distinguish between the locked cache and DMA features.</P>
