//
// TITLE:   DSP281x Event Manager GP Timer example program.
//
// ASSUMPTIONS:
//
//          This program requires the DSP281x V1.00 header files.  
//          As supplied, this project is configured for "boot to H0" operation.
//
//          Other then boot mode pin configuration, no other hardware configuration
//          is required.  
//
// DESCRIPTION:
//
//          This program sets up EVA Timer 1, EVA Timer 2, EVB Timer 3
//          and EVB Timer 4 to fire an interrupt on a period overflow.  
//          A count is kept each time each interrupt passes through
//          the interrupt service routine. 
//
//          EVA Timer 1 has the shortest period while EVB Timer4 has the
//          longest period.
//
//          Watch Variables:
//
//                EvaTimer1InterruptCount;
//                EvaTimer2InterruptCount;
//                EvbTimer3InterruptCount;
//                EvbTimer4InterruptCount;
