20. CRC Calculation
The Cyclic Redundancy Check (CRC) operation detects an error in data blocks. The microcomputer uses a generator
polynomial of CRC_CCITT (X
The CRC code consists of 16 bits which are generated for each data block in given length, separated in 8 bit units.
After the initial value is set in the CRCD register, the CRC code is set in that register each time one byte of data is
written to the CRCIN register. CRC code generation for one-byte data is finished in two cycles.
Figure 20.1 shows the CRC Circuit Block Diagram. Figure 20.2 shows the CRC-related Registers.
Figure 20.3 shows the Calculation Example using the CRC Operation.

When data is w ritten to the CRCIN register after setting the initial value in
the CRCD register, the CRC code can be read out from the CRCD
register.
