9.2.6 Identify-Drive - ECH
The Identify-Drive command enables the host to receive parameter information from the CompactFlash
card controller. This command has the same protocol as the Read-Sector(s) command. The parameter
words in the buffer have the arrangement and meanings defined in Table 9-8. All reserved bits or words
are zero. Table 9-8 gives the definition for each field in the Identify-Drive information.
