4.5.1 Calculation of CRC-16
The communication method of the CRC system divides the information that should be sent with the
generation polynomial expression and add the remainder behind information.
The generation polynomial expression is as follows.
Calculate the data from the slave address to last data with the following procedure.
1) Initialize the data of CRC-16 (It makes X): (=FFFFH)
2) Exclusive OR of data 1 and X: (EX-OR) →X
3) Shift X to the right 1 bit →X 
4) If a carry comes out, take A001H and Ex-OR. Move to 5) if a carry does not come out.
5) Repeat the above 3) to 4) until it shifts 8 times.
6) Next data and X of Ex-OR →X
7) With from 3) to 5) same.
8) Repeats it to the last data.
9) The message is made in order to the upper class from the subordinate class of calculated 16 bits
