- Violates MISRA 2004 Required Rule 8.5, object/function definition in header file.<br>
|

Function definitions in header files are used to allow 'inlining'.
|

- Violates MISRA 2004 Required Rule 18.4, declaration of union type or object of union type: '{...}'.<br>
|

Unions are used for effective representation of core registers.

- Violates MISRA 2004 Advisory Rule 19.7, Function-like macro defined.<br>

Function-like macros are used to allow more efficient code.
