An example of the CRC operation circuit is shown below.
The code when 01H is sent LSB first is (1000 0000). Therefore, the CRC code from generation polynomial X
The modulo-2 operation is performed based on the following formula.
0 + 0 = 0
0 + 1 = 1
1 + 0 = 1
1 + 1 = 0

Therefore, the CRC code becomes
