Part I: In EVB Mode (Debug Mode) Part II: In POD Mode (Auto Mode)

Requirement: You must demo your program on a dragon12-Light board.

Goal: To become familiar with using clock frequency, running your program automatically in POD Mode, using Dragon12-Light boards as well as improving your programming skills.

Project: Please read Chapter 3 of your textbook for writing subroutines and Chapter 4 of your textbook; then, write assembly programs to do the following:

Flash all LEDs in one Hz frequency when running your program in the EVB mode (also called debug mode). In EVB mode, the clock frequency for instructions is 24MHz.

Flash all LEDs in one Hz frequency when running your program in the POD mode (also called auto mode). In POD mode, the clock frequency for instructions is 4MHz.

You must write a subroutine that consumes exactly one second of CPU time. To achieve the flashing effect, in your main program, you need to turn on all the LEDs, then, call this subroutine. Turn off all LEDs, then, call this subroutine.

Your program must flash LEDs continuously in one Hz frequency until a Reset.
