I have a customer that is working with the XMC1000 series devices. They are converting from another microcontroller provider, and were previously using a CRC engine in order to meet the UL1998 Table A2.1 Component 6.2 requirements for memory checking. It looks like we can accomplish the specification requirements with ECC. Can you possibly elaborate on the design intentions of the device in order to meet UL and other certifications?

Seems to me that this UL 1998 is a safety standard for software programming. And your customer had previously used CRC engine to check the integrity of the data in flash or ROM to ensure that there is no bit errors. This feature can be replaced with XMC1000 ECC which the on-chip RAM and flash modules check ECC information during read accesses and
in case of an error a signal is generated.
