+<p>CMSIS-CORE violates the following MISRA-C:2004 rules:</p>
+<ul>
+<li>Required Rule 8.5, object/function definition in header file.<br/>
+ Violated since function definitions in header files are used for function inlining'.</li>
+</ul>
+<ul>
+<li>Advisory Rule 12.4, Side effects on right hand side of logical operator.<br/>
+ Violated because volatile is used for core register definitions.</li>
+</ul>
+<ul>
+<li>Advisory Rule 14.7, Return statement before end of function.<br/>
+ Violated to simplify code logic.</li>
+</ul>
+<ul>
+<li>Required Rule 18.4, declaration of union type or object of union type: '{...}'.<br/>
+ Violated since unions are used for effective representation of core registers.</li>
+</ul>
+<ul>
+<li>Advisory Rule 19.4, Disallowed definition for macro.<br/>
+ Violated since macros are used for assembler keywords.</li>
+</ul>
+<ul>
+<li>Advisory Rule 19.7, Function-like macro defined.<br/>
+ Violated since function-like macros are used to generate more efficient code.</li>
+</ul>
+<ul>
+<li>Advisory Rule 19.16, all preprocessing directives must be valid.<br/>
+ Violated to set default settings for macros.</li>
+</ul>
+<p>&lt;device&gt;.h files generated by <b>SVDConv.exe</b> violate the following MISRA-C:2004 rules:</p>
+<ul>
+<li>Advisory Rule 20.2, Re-use of C90 identifier pattern.<br/>
+ Violated since CMSIS macros begin with '__'. Since CMSIS is developed and verified with various compilers this approach is acceptable and avoids conflicts with user symbols.</li>
+</ul>
+<ul>
+<li>Advisory Rule 19.1, Declaration before #include.<br/>
+ Violated since Interrupt Number Definition Type (IRQn_Type) must be defined before including the core header file. </li>
+</ul>
