For AES-CTR operations, the following configuration parameters are required:
The length field can have any value. If a data stream is finished and the next data stream uses the same key and control, only the IV and length field can be written with a new value. The length field can be 0, resulting in continued processing.
If the result IV must be read by the host, the save_context bit must be set to 1 after processing the programmed number of bytes.
