After default value is written to the CRCD
register, the CRC code can be read from the
CRCD register by writing data to the CRCIN
register. Bit position of the default value is
inversed. The inversed value is read as the CRC
code.

19. CRC Calculation
The CRC (Cyclic Redundancy Check) calculation detects an error in data blocks. A generator polynomial
of CRC_CCITT (X16 + X12 + X5 + 1) generates CRC code.
The CRC code is a 16-bit code generated for a block of data of desired length. This block of data is in 8-bit
units. The CRC code is set in the CRCD register every time one-byte data is transferred to the CRCIN
register after a default value is written to the CRCD register. CRC code generation for one-byte data is
completed in two cycles.
Figure 19.1 shows a block diagram of a CRC circuit. Figure 19.2 shows registers related to CRC. Figure
19.3 shows an example of the CRC calculation.
