Stores CRC code
The code resulting from sending 0116 in LSB first mode is (1000 0000). Thus the CRC code in the generating polynomial,
(X16 + X12 + X5 + 1), becomes the remainder resulting from dividing (1000 0000) X16 by (1 0001 0000 0010 0001) in
conformity with the modulo-2 operation.
Thus the CRC code becomes (1001 0001 1000 1000). Since the operation is in LSB first mode, the (1001 0001 1000 1000)
corresponds to 118916 in hexadecimal notation. If the CRC operation in MSB first mode is necessary in the CRC operation
circuit built in the M16C, switch between the LSB side and the MSB side of the input-holding bits, and carry out the CRC
operation. Also switch between the MSB and LSB of the result as stored in CRC data.
