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: 0xFA. The method of calculating LRC check code value: 0x01+
0x03 + 0x00 + 0x00 + 0x00 + 0x02 = 0x06, the result 0xFA is got by getting the inverse values of
every bit of 0x06 and then adding 1 to the final inverse value.
