  \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.
