Abstract:
1. A method for processing noise interference in a data accessing device with a SATA (Serial Advanced Technology Attachment) interface, the method comprising: an error detecting step for detecting whether there is a CRC (Cyclic Redundancy Check) error, whether an reception error primitive (R_ERR primitive) is received, whether an improper primitive is received, or whether a LINK layer error is detected, and repeating this step if there is no any error; a type detecting step for detecting whether an incoming FIS (Frame Information Structure) is a data type FIS and going back to the error detecting step when the FIS is not data type; a responding step for asserting the CHECK bit of the ATAPI Status Register when the incoming FIS is data type; and sending back the response.
