/*********************************************************************
* File: GlobalVariableDefs.c                                         *
* Description: Contains global variable definitions used in the TEC  *
*   application.  This file is similar to the file of the  same name *
*   found in the DSP28 header files v0.58, except some TEC           *
*   application specific variables have been declared at the end.    *
* DSP: TMS320F2812                                                   *
* Author: David M. Alter                                             *
* Function List: Not applicable                                      *
* History:                                                           *
*   11/05/02 - Original, based on DSP28 header files v0.58 (D. Alter)*
* Notes: none                                                        *
