<a name="details" id="details"></a><h2 class="groupheader">Description</h2>
<p>Cortex-M7 processors include a memory system, which includes an optional MPU and Harvard 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>
<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>
<dl class="section note"><dt>Note</dt><dd>After reset, you must invalidate each cache before enabling it.</dd></dl>
<p>The functions are grouped for:</p>
<ul>
<li><a class="el" href="group___icache__functions__m7.html">I-Cache Functions</a></li>
<li><a class="el" href="group___dcache__functions__m7.html">D-Cache Functions</a> </li>
