**  Function:
**    This C code is written for using with the TI's C54 Code Composer
**    Studio platform. It serves as the main program for C5402 DSP. It
**    communicates and controls AIC10/11 CODECs on the (daughter) EVM;
**    and calls other application routines, include: DTMF tone
**    generation, security voice system, acoustic echo cancellation
**    (AEC), and voice over internet protocol (VoIP).
