	Description: This module is responsible for providing a
32
	debug interface to the system.  Currently, the only
33
	debugging that is available is through the on-board
34
	UART (which is used by the main application as well) in
35
	addition to the LED hooked up at PORTD bit 6.

	Function Name: DebugInt_init
59
	Function Description: This function is responsible for
60
	initializing the debug module.  It sets up the debug LED
61
	as well as any other debugging that will be done.  The 
62
    LED blinks four times, which indicates to the user
63
    that the system is available for re-programming if 
64
    necessary.  This works because the data lines on the
65
    OV6620 are still tri-stated at this point, but won't
66
    be for long after this function returns.

	Inputs:  none
