se050 ed448 question

Dear 

I am finding conflicting information across documents regarding the SE050E's support for the Ed448 curve, and my own attempts to implement it have been unsuccessful.

Could you please confirm once again whether the SE050E supports Ed448?

When I execute the SE050E API to verify a certificate signature, the `WriteECKey` operation fails and returns error code `0x6985` (curve `0x42`), which indicates "Conditions of use not satisfied."
Upon further investigation, it appears that the "448" support on the SE050E refers to X448 DH rather than Ed448 signatures; could you please verify this?
