Flushes the current contents of the instruction cache.
void FlushCodeCache ();
Because flushing this cache degrades performance of the CPU, you should call this routine only when absolutely necessary.
On processors with a copy-back data cache, FlushCodeCache also flushes the data cache before it flushes the instruction cache, to ensure that any instructions subsequently copied to the instruction cache are not copied from stale RAM.
