以下函数验证是否存在 MMA 错误注入测试序列。以下代码是完全取决于用户的最终实现的示例。

volatile unit8_t track_exception = 0;
void test_fun(void)

            overflow_exception();//generate exception
            break;
        case 1:
            clear_mma();
            track_exception = track_exception+1;
            appLogPrintf("Under flow exception\n"); /*Only for debug, remove*/
            underflow_exception(); // generate exception
            break;
