 LRC check (Check sum)
LRC check code is the value by firstly getting the inverse values of every bit of the result value of
addition operation of the data from communication ID to the last data content (Hex.) and then
adding 1 to the final inverse value.
For instance, LRC check code value: 16#FA. The method of calculating LRC check code value:
16#01+ 16#03 + 16#00 + 16#00 + 16#00 + 16#02 = 16#06, the result 16#FA is got by getting the
inverse values of every bit of 16#06 and then adding 1 to the final inverse value.
