摘要： A cyclic redundancy check (CRC) management method performed in a serial advanced technology attachment (SATA) interface and a data storage device using the CRC management method. A host interface connected to the SATA interface performs CRC computation on transmitted data to generate a first CRC code, determines whether a host interface block error or a data integrity error occurs, or the status of a data storage device needs to be reported to the host interface, generates a second CRC code, which is different from the first CRC code, according to the determination result. If a frame including the transmitted data and the second CRC code is transmitted to a host, the host performs CRC computation on a data FIS in the transmitted data to expect the first CRC code. Since the CRC code in the transmitted data is the second CRC code, the host recognizes that the transmitted data is wrong and provides an error notification to the data storage device. Accordingly, the host can be informed of the host interface block error, the data integrity error, or the status error of the data storage device, not a protocol error in the SATA interface.

摘要： A method of controlling a power saving mode used in a serial advanced technology attachment (SATA) interface. The method of controlling a power saving mode used in a SATA interface for data transmission between a transmitter and a receiver includes: requesting the receiver to enter one of a plurality of power saving modes in a SATA protocol using the transmitter; and selecting one of the power saving modes using the receiver. In the method of controlling a power saving mode in a SATA interface, since a power saving mode can be selected independently of a power saving mode requested by a transmitter, a system can operate in a power saving mode that is suitable for the required properties of the system in accordance with a SATA protocol. Furthermore, the properties of the system required by a user can be realized by selecting a user-defined power saving mode.
摘要翻译：控制在串行高级技术附件（SATA）接口中使用的省电模式的方法。控制在SATA接口中用于发射机和接收机之间的数据传输的省电模式的方法包括：使用发射机请求接收机进入SATA协议中的多个省电模式之一; 并使用接收器选择一种省电模式。在SATA接口中控制省电模式的方法中，由于可以独立于发射机所要求的功率节省模式来选择功率节省模式，所以系统可以以适于所需性能的功率节省模式进行操作该系统符合SATA协议。此外，可以通过选择用户定义的省电模式来实现用户所需的系统的属性。
