5.3 Host Commands (26) IDENTIFY DEVICE (X 'EC') The host system issues the IDENTIFY DEVICE command to read parameter information from the device. When it receives the command, the device prepares the parameter information to be sent to the host. Next, the device sends the PIO Setup FIS to the host, then sends the parameter information including a 512-byte data. Table 5.33 shows the values of the parameter words and the meaning in the buffer. • Error reporting conditions (1) A SATA communication error occurred (ST = 51h, ER = 0Ch). At command issuance (Shadow Block Registers setting contents) CM 1110110 0 DH x x x x xx CH xx CL xx SN xx SC xx FR xx At command completion (Shadow Block Registers contents to be read) ST Status information DH x x x x xx CH xx CL xx SN xx SC xx ER Error information C141-E293 5-103
