- * @file    SPIRIT_Aes.h
-  * @author  VMA division - AMS
-  * @version 3.2.2
-  * @date    08-July-2015
- * @brief   Configuration and management of SPIRIT AES Engine.
-  *
- * @details
- *
- * In order to encrypt data, the user must manage the AES_END IRQ.
- * The data have to be splitted in blocks of 16 bytes and written
- * into the <i>AES DATA IN registers</i>. Then, after the key is written
- * into the <i>AES KEY registers</i>, a command of <i>Execute encryption</i>
- * has to be sent.
- *
- * <b>Example:</b>
- * @code
- *
- *  SpiritAesWriteDataIn(data_buff , N_BYTES);
- *  SpiritAesExecuteEncryption();
- *
- *  while(!aes_end_flag);       // the flag is set by the ISR routine which manages the AES_END irq
- *  aes_end_flag=RESET;
- *
- *  SpiritAesReadDataOut(enc_data_buff , N_BYTES);
- *
- * @endcode
- *
- * In order to decrypt data, the user must manage the AES_END IRQ and have a decryption key.
- * There are two operative modes to make the data decryption:
- * <ul>
- * <li> Derive the decryption key from the encryption key and decrypt data directly
- * using the <i>SpiritAesDeriveDecKeyExecuteDec()</i> function
- *
- * <b>Example:</b>
- * @code
- *
- *  SpiritAesWriteDataIn(enc_data_buff , N_BYTES);
- *  SpiritAesDeriveDecKeyExecuteDec();
- *
- *  while(!aes_end_flag);       // the flag is set by the ISR routine which manages the AES_END irq
- *  aes_end_flag=RESET;
- *
- *  SpiritAesReadDataOut(data_buff , N_BYTES);
- *
- * @endcode
- * </li>
- *
- * <li> Derive the decryption key from the encryption key using the <i>SpiritAesDeriveDecKeyFromEnc()</i>
- * function, store it into the <i>AES KEY registers</i> and then decrypt data using the
- * <i>SpiritAesExecuteDecryption()</i> function
- *
- * <b>Example:</b>
- * @code
- *
- *  SpiritAesWriteDataIn(key_enc , 16);
- *  SpiritAesDeriveDecKeyFromEnc();
- *
- *  while(!aes_end_flag);       // the flag is set by the ISR routine which manages the AES_END irq
- *  aes_end_flag=RESET;
- *
- *  SpiritAesReadDataOut(key_dec , 16);
- *
- *  SpiritAesWriteKey(key_dec);
- *  SpiritAesWriteDataIn(enc_data_buff , 16);
- *  SpiritAesExecuteDecryption();
- *
- *  while(!aes_end_flag);       // the flag is set by the ISR routine which manages the AES_END irq
- *  aes_end_flag=RESET;
- *
- *  SpiritAesReadDataOut(data_buff , N_BYTES);
- *
- * @endcode
- * </li>
- * </ul>
