You can therefore refer to <a href="http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0497a/CIHIGCIF.html">ARM's documentation on them</a>.</p> <p>What exactly are you looking for? Normally, you'd access these registers only through the CMSIS interface, the NVIC_* functions.</p><div style="clear:both;"></div>
