30<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>
31<P>In PowerPC architecture jargon, this feature is referred to as unlocking the instruction cache.&nbsp;We use the word &quot;freeze&quot; for the Wii to distinguish between the locked cache and DMA features.</P>
