HECK_USER_KEY_0_CRC FALSE Default value is FALSE TRUE will validate USER_KEY_0 key stored in eFuse by calculating its CRC and comparing with CRC provided in XNVM_EFUSE_EXPECTED_USER_KEY0_CRC. CRC verification is done after programming the key to verify the key is programmed properly or not, if not library error outs the same. NOTE: Please make sure if intention is to check only CRC of the provided key and not programming USER_KEY_0 key then do not modify XNVM_EFUSE_WRITE_USER_KEY_0 (TRUE will Program key).
