 * Some digital debugs. A digital debug is 2 signals on the 2 LED outputs,
 * turned on and off depending on some condtions given in the code.
 * Only one can be selected, by defining DIGITAL_DEBUG_MASK to the value
 * of the debug.
 * In the code one can do like:
 * if (whatever_condition) {
 *      DebugOut.Digital[0] |= DEBUG_MYOWNDEBUGGER;
 * } else {
 *      DebugOut.Digital[0] &= ~DEBUG_MYOWNDEBUGGER;

 *      DebugOut.Digital[1] |= DEBUG_MYOWNDEBUGGER;
 * } else {
 *      DebugOut.Digital[1] &= ~DEBUG_MYOWNDEBUGGER;
 * }
 *
 * Digital debugs may be added as desired, and removed when the mystery
 * at hand is resolved.
