I2C_FLAG_RXNE ...). - * - When to use: - * - This function could be used for specific applications or in debug phase. - * - It is suitable when only one flag checking is needed (most I2C events - * are monitored through multiple flags). - * - Limitations: - * - When calling this function, the Status register is accessed. Some flags are - * cleared when the status register is accessed.
