// TITLE: AES ECB Encryption
//
//! \addtogroup driver_example_cm_list
//! <h1>AES ECB Encryption Example (CM)</h1>
//!
//! This example encrypts block cipher-text using AES128 in ECB mode. It does
//! the encryption first without uDMA and then with uDMA. The results are
//! checked after each operation.
//!
//! \b External \b Connections \n
//! - None
//!
//! \b Watch \b Variables \n
//! - \b errCountGlobal - Error Counter. It should be zero.
//! - \b testStatusGlobal - Test status. It should be equal to PASS.
//!

//! \addtogroup driver_example_cm_list
//! <h1>AES ECB De-cryption Example (CM)</h1>
//!
//! This example de-crypts block cipher-text using AES128 in ECB mode. It does
//! the de-cryption first without uDMA and then with uDMA. The results are
//! checked after each operation.
//!
//! \b External \b Connections \n
//! - None
//!
//! \b Watch \b Variables \n
//! - \b errCountGlobal - Error Counter. It should be zero.
//! - \b testStatusGlobal - Test status. It should be equal to PASS.
