Hello sir,
This feature is part of the memory access management. Both ICODE Slix and ICODE Slix2 have some level of security but, yes ICODE Slix2 does have additional security features.
My recommendation would be to please request the secure file AN158930 (ICODE SLI/SLIX/SLIX2/DNA Memory Access Management). Where different recommedations are disclosed.
Best Regards,
Fabian
