ABSTRACT:
A method for reading non-standard register of Serial Advanced Technology Attachment (SATA) devices discloses an unused input parameter of standard command setting up as an executive parameter. While receiving the standard command, a SATA host controller converts the executive parameter and the standard command into input frame information structure (FIS) that is sent to the SATA devices for the SATA devices to detect the executive parameter for reading corresponding value of non-standard register and saving the value into an output register of the SATA devices. The value of the non-standard register is converted into output frame information structure for being sent to the SATA host controller and the value of the non-standard register is saved to the output register of the SATA host controller. Then by reading the value of the output register of the SATA host controller, the value of the non-standard register is learned.
