The CRC function includes the following hardware.
• CRC operation circuit for detection of data block errors
• Generation of 16-bit CRC code using a CRC-CCITT (X
• CRC code is set to the CRCD data register each time 1-byte data is transferred to the CRCIN register, after the initial
any length in 8-bit units
value is set to the CRCD register.
