Description:
 def write_registers(self, registeraddress, values):
 """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 """
