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.
