6.3.4.1.1 CRC Error Status

The NVMCRCCON.CRCEC field shows the error status of the most recent CRC operation. Possible errors include:

• Invalid address (start address is greater than end address)
• Flash ECC DED error
• Security access control error (attempts to access a memory region or perform an operation that is not permitted under the current security settings)

If the CRC operation completes successfully (CRCEC=00), the NVMCRCDATA register is updated with the calculated CRC-32 checksum or state. If an error occurs, NVMCRCDATA is set to 0x0000_0000.
