For CBC-MAC operations, the following configuration parameters are required:
The input data can end misaligned for CBC-MAC operations. If this is the case, the crypto core internally pads the last input data block.
The length field can have any value. If a data stream is finished and the next data stream uses the same key and control, writing only a part of the next context is not allowed. A new data stream must always write the complete context. The length field must never be written with zeroes.
