____________________________________________________________________________________________________

This directory contains an example ADSP-BF533 blink led project that initializes the flash.
Because the LEDs are linked to the flash rather than to the DSP, the flash must be set in order to 
blink the LEDs.

I.    FUNCTIONAL DESCRIPTION

This code toggles the LEDs.
 
This example utilizes the flash on the EZ-KIT to access the LEDs.


II.   IMPLEMENTATION DESCRIPTION


The main file calls:

1. the Flash_Setup subroutine to initialize the flash.


III.  OPERATION DESCRIPTION

- Check SW9 settings on BF533 EZ-KIT.  Pins 1-4 should be ON.
- Open the project "ADSP-BF533_EZ-KIT_BlinkLeds.dpj" in the VisualDSP Integrated Development Environment (IDDE).
- Under the "Project" tab, select "Build Project" (program is then loaded automatically into DSP).
- Select "Run" from the "Debug" tab on the menu bar of VisualDSP.
- The LEDs should be toggling.  Press either SW4, SW5, SW6, or SW7 for different LED toggling patterns.
