| /** |

| * |
| * \par Purpose |
| * |
| * Standard output methods for reporting debug information, warnings and |
| * errors, which can be easily be turned on/off. |
| * |
| * \par Usage |
| * -# Initialize the DBGU using TRACE_CONFIGURE() if you intend to eventually |
| * disable ALL traces; otherwise use DBGU_Configure(). |
| * -# Uses the TRACE_DEBUG(), TRACE_INFO(), TRACE_WARNING(), TRACE_ERROR() |
| * TRACE_FATAL() macros to output traces throughout the program. |
| * -# Each type of trace has a level : Debug 5, Info 4, Warning 3, Error 2 |
| * and Fatal 1. Disable a group of traces by changing the value of |
| * TRACE_LEVEL during compilation; traces with a level bigger than TRACE_LEVEL |
| * are not generated. To generate no trace, use the reserved value 0. |
| * -# Trace disabling can be static or dynamic. If dynamic disabling is selected |
| * the trace level can be modified in runtime. If static disabling is selected |
| * the disabled traces are not compiled. |
| * |
| * \par traceLevels Trace level description |
| * -# TRACE_DEBUG (5): Traces whose only purpose is for debugging the program, |
| * and which do not produce meaningful information otherwise. |
| * -# TRACE_INFO (4): Informational trace about the program execution. Should |
| * enable the user to see the execution flow. |
| * -# TRACE_WARNING (3): Indicates that a minor error has happened. In most case |
| * it can be discarded safely; it may even be expected. |
| * -# TRACE_ERROR (2): Indicates an error which may not stop the program execution, |
| * but which indicates there is a problem with the code. |
| * -# TRACE_FATAL (1): Indicates a major error which prevents the program from going |
| * any further. |
