Value after reset: 0 0
CRCDOR is a readable and writable register.
Since its initial value is 0000h, rewrite the CRCDOR register to perform calculation using a value other than the initial
value.
Data written to the CRCDIR register is CRC calculated and the result is stored in the CRCDOR register. If the CRC code
is calculated following the transferred data and the result is 0000h, there is no CRC error.
