 * 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.
