Hi!
I'm currently testing the AES co-processor of the CC1110.
I have implemented and tested both encryption and decryption using CBC and compared outputvalues to reference data. It works and it's correct.
But I cannot get CBC-MAC to work.
According to the spec ENCCS.MODE = CBC-MAC until the last block, then ENCCS.MODE = CBC. So far so good.
It also says I should make sure mode is set when initiating it. So ENCCS.MODE = CBC-MAC when I'm loading key and iv/nonce.
What I'm I doing wrong/missing?
