  \page CMSIS_MISRA_Exceptions  MISRA-C:2004 Compliance Exceptions
  CMSIS violates the following MISRA-C:2004 rules:

   \li Required Rule 8.5, object/function definition in header file.<br>
     Function definitions in header files are used to allow 'inlining'.

   \li Required Rule 18.4, declaration of union type or object of union type: '{...}'.<br>
     Unions are used for effective representation of core registers.

   \li Advisory Rule 19.7, Function-like macro defined.<br>
     Function-like macros are used to allow more efficient code.
