 149 <p>Functions for level-1 instruction and data cache. </p>
 150 <p>Enhanced Cortex processors (like M7 and M55) include a memory system, which includes an optional Harvard level-1 data and instruction cache with ECC. The optional CPU cache has an instruction and data cache with sizes of <span class="XML-Token">[0;4;8;16;32;64]KB</span>. Both instruction and data cache RAM can be configured at implementation time to have Error Correcting Code (ECC) to protect the data stored in the memory from errors.</p>
 151 <p>All cache maintenance operations are executed by writing to registers in the memory mapped System Control Space (SCS) region of the internal PPB memory space.</p>
 152 <dl class="section note"><dt>Note</dt><dd>After reset, you must invalidate each cache before enabling it.</dd></dl>
 153 <p>The functions are grouped for:</p><ul>
 154 <li><a class="el" href="group__Icache__functions__m7.html">I-Cache Functions</a></li>
 155 <li><a class="el" href="group__Dcache__functions__m7.html">D-Cache Functions</a> </li>
