Note 1: Commands indicated with Y in the NVM column indicate that these
commands are stored and restored using the STORE_USER_ALL and
RESTORE_USER_ALL commands, respectively.
Note 2: Commands with a default value of NA indicate "not applicable".
Commands with a default value of FS indicate "factory set on a per part
basis".
Note 3: The LTM4700 contains additional commands not listed in Table 7.
Reading these commands is harmless to the operation of the IC; however,
the contents and meaning of these commands can change without notice.

Note 4: Some of the unpublished commands are read-only and will
generate a CML bit 6 fault if written.
Note 5: Writing to commands not published in Table 7 is not permitted.
Note 6: The user should not assume compatibility of commands
between different parts based upon command names. Always refer to
the manufacturer's data sheet for each part for a complete definition
of a command's function. ADI strives to keep command functionality
compatible between all ADI devices. Differences may occur to address
specific product requirements.
