VERVIEW
IDENTIFY DEVICE (ECh) enables the host to receive parameter information from the SSD. When the
command executes, the SSD sets the BSY bit, prepares to transfer the 256 words of SSD identification
data to the host, sets the DRQ bit, clears the BSY bit, and then generates an interrupt. The host can then
transfer the data by reading the data register. All reserved bits or words are all zero.
It is recommended that the user reference INCITS Information
