‘-x’
     Output as hexadecimal two-byte units.  Equivalent to ‘-t x2’.

Outputs 16-bit integers in the *native byte order* of the machine.
Which may be either big-endian or little-endian depending on the
machine.  Not portable.  Depends upon the machine it is run upon.

The -tx1 option above is portable because it outputs 1-byte units
instead of 2-byte units which is independent of endianess.
