59.4.4 Last Output Data Mode

Last Output Data mode is used to generate cryptographic checksums on data (MAC) by means of a cipher block chaining encryption algorithm (e.g., the CBC-MAC algorithm).

After each end of encryption/decryption, the output data are available on the output data registers for Manual and Auto modes.

AESB_MR.LOD allows retrieval of only the last data of several encryption/decryption processes.

Those data are only available on the Output Data registers (AESB_ODATARx).
