Card Module sequence

hello all!

I'm writing you because I'm developing a new card module for a smart card and I wonder if somebody could be so kind of telling me the different sequences of commands that are invoked in the following processes:
- enrollment
- signature creation
- asymmetric decryption

I'm working in the enrollment process and I'm trying to implement the different functions needed to this process. I have looked at the documentation, but in some cases I do not have clear what to do in some functions and the values to return.

Could you help me, please?

Best regards,
Antonio.
