+ 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.
