Identify Device (X 'Ec') - Fujitsu MHY2250BH Product/Maintenance Manual

(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.
