Preset the 16 bit register to hexadecimal​, call this register as CRC register; 2. Isolate the first 8 bit data with the lower bit of the CRC register and put the result in the CRC register; 3. shift the contents of the register one bit to the right (towards the low bit), fill the highest bit with 0, and check the lowest bit; 4. if the lowest bit is 0: repeat step 3 (shift again) if the lowest bit is 1: the CRC register is iso-orthogonal to the polynomial A001 (1010 0000 0000 0001); 5. Repeat steps 3 and 4 until it is shifted right 8 times so that the entire 8 bit data is all processed; 6. repeat steps 2 to 5 for the next 8 bit data; The final CRC register obtained is the CRC code (the CRC code obtained is low before high).
