// ASSUMPTIONS:

//

// This program requires the DSP2833x header files.

//

// As supplied, this project is configured for "boot to FLASH"

// operation. The 2833x Boot Mode table is shown below.

// For information on configuring the boot mode of an eZdsp,

// please refer to the documentation included with the eZdsp,
