6.4.1.7 Flash Table Transport CRC

Look-up tables, such as sequences, are CRC-verified while being transferred from flash. Once the table is written to internal memory, hardware calculates a CRC of the data and compares it to the CRC value that was calculated while the table was being read from flash. If the CRC is incorrect, this test will take action.
