42 CMSIS violates the following MISRA-C:2004 rules:
44 \li Required Rule 8.5, object/function definition in header file.<br>
45 Function definitions in header files are used to allow 'inlining'.
47 \li Required Rule 18.4, declaration of union type or object of union type: '{...}'.<br>
48 Unions are used for effective representation of core registers.
50 \li Advisory Rule 19.7, Function-like macro defined.<br>
51 Function-like macros are used to allow more efficient code.
