* @brief Status type generally used in AMiRo-OS. |
|
50 |
* @details By definition, the most significant bit (MSB) indicates whether an error occurred (e.g. the function call failed). |
|
51 |
* All other bits can be used to specify the issue in more detail. |
|
52 |
* If the MSB is unset, all other bits can still be used to indicate and specify non-critical warnings. |
|
53 |
* As a result, a value of 0 (no bit set) indicates a flawles success. |
