| Module Name: DebugInterface.c |
| Module Date: 04/15/2004 |
| Module Auth: John Orlando |
| |
| Description: This module is responsible for providing a |
| debug interface to the system. Currently, the only |
| debugging that is available is through the on-board |
| UART (which is used by the main application as well) in |
| addition to the LED hooked up at PORTD bit 6. |

| Function Name: DebugInt_init |
| Function Description: This function is responsible for |
| initializing the debug module. It sets up the debug LED |
| as well as any other debugging that will be done. The |
| LED blinks four times, which indicates to the user |
| that the system is available for re-programming if |
| necessary. This works because the data lines on the |
| OV6620 are still tri-stated at this point, but won't |
| be for long after this function returns. |
| Inputs: none |
| Outputs: none |
