Preset the 16 bit register to hexadecimal FFFF, 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. check the lowest bit by shifting the contents of the register one bit to the right (towards the lower bit) and filling the highest bit with a 0;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. repeating steps 2 through 5 for the next 8 bit data;7. The final CRC register obtained is the CRC code (the CRC code obtained is low before high).
