docs: Write integers to 16-bit registers in the slave.
  
          The slave register can hold integer values in the range 0 to 65535 ("Unsigned INT16").
  
          Uses Modbus function code 16.
  
          The number of registers that will be written is defined by the length of the ``values`` list.
  
          Args:
              * registeraddress (int): The slave register start address (use decimal numbers, not hex).
              * values (list of int): The values to store in the slave registers.
  
          Any scaling of the register data, or converting it to negative number (two's complement)
          must be done manually.
  
          Returns:
              None
  
          Raises:
              ValueError, TypeError, IOError
