The Contents of Non-Volatile Memory Request command causes the Target unit to
transmit, in the response, the contents of its non-volatile memory.  Two values are included
in the data segment of the command: an “Offset” data word that determines how many bytes
from the beginning of the Non-Volatile memory structure that the desired data begins, and a
“Length” data word that determines the total number of bytes to be transmitted back to the
Source unit.

NOTE: sending a “Length” data word value of zero will cause the Target unit to respond
with the rest of the structure (from offset to the end) - the number of bytes returned in the
response will reflect the actual number of bytes involved.
