The Identify Device command enables the host to receive parameter information from the CompactFlash
Storage Card. 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 as below. All reserved bits or words are zero.
Hosts should not depend on Obsolete words in Identify Device containing 0. Table 47 specifies each field in the
data returned by the Identify Device Command. In Table as below, X indicates a numeric nibble value specific to
the card and aaaa indicates an ASCII string specific to the particular drive.
