Checking Steps:
1. The preset 16 bit register is hexadecimal FFFF, is called CRC register;
2. The first 8 bit data is different from the lower part of the CRC register or put the result in the CRC register;
3. Move the contents of the register to the right one bit (towards the low), fill the highest bit with 0, and check the lowest bit;
4. If the lowest position is 0: repeat step 3 (shift again) If the lowest position is 1: the CRC register is XOR with polynomial A001 (1010 0000 0000 0001);
