- * @brief
- *   Enable Serial Wire Output (SWO) pin.
- *
- * @details
- *   The SWO pin (sometimes denoted SWV, serial wire viewer) allows for
- *   miscellaneous output to be passed from the Cortex-M3 debug trace module to
- *   an external debug probe. By default, the debug trace module and pin output
- *   may be disabled.
- *
- *   Since the SWO pin is only useful when using a debugger, a suggested use
- *   of this function during startup may be:
- * @verbatim
- * if (DBG_Connected())
- * {
- * DBG_SWOEnable(1);
- * }
- * @endverbatim
- *   By checking if debugger is attached, some setup leading to higher energy
- *   consumption when debugger is attached, can be avoided when not using
- *   a debugger.
- *
- *   Another alternative may be to set the debugger tool chain to configure
- *   the required setup (similar to the content of this function) by some
- *   sort of toolchain scripting during its attach/reset procedure. In that
- *   case, the above suggested code for enabling the SWO pin is not required
- *   in the application.
- *
- * @param[in] location
- *   Pin location used for SWO pin on the application in use.
