Figure . illustrates this algorithm of checking CRC errors.
Symbol ’⊕’ indicates XOR operation. “n” means a number of data bits.
START
xFFFF →CRC Register
CRC Register ⊕ next byte of the message →CRC Register
→n
Shift CRC Register right one bit
Over low?
NO
YES
CRC Register ⊕ xA
→CRC Register
n + →n
n > ?
NO
YES
CRC Register ⊕ A
h →CRC Register
Is message complete?
NO
YES
