c) Function code '06H': write to single register
This function is used to save a fragment of data in the PSU memory. For
instance, changing the voltage to 19.99V. After multiplying the value by
100 and converting it to hexadecimal format, it should be written to the
slave register with address 1000H (the slave address code is 01).
