  * @version 3.2.2
  * @date    08-July-2015
 * @brief   Configuration and management of SPIRIT VCO-RCO calibration.
  *
 * @details
 *
 * This module allows the user to set some parameters which deal
 * with the oscillators calibration.
 * The state machine of Spirit contemplates some optional calibrating operations
 * in the transition between the READY and the LOCK state.
 * The user is allowed to enable or disable the automatic RCO/VCO calibration
 * by calling the functions <i>@ref SpiritCalibrationVco()</i> and <i>@ref SpiritCalibrationRco()</i>.
 * The following example shows how to do an initial calibration of VCO.
 *
 * <b>Example:</b>
 * @code
 *  uint8_t calData;
 *
 *  SpiritCalibrationVco(S_ENABLE);
 *  SpiritCmdStrobeLockTx();
 *
 *  while(g_xStatus.MC_STATE != MC_STATE_LOCK){
 *      SpiritRefreshStatus();
 *  }
 *
 *  calData = SpiritCalibrationGetVcoCalDataTx();
 *  SpiritCalibrationSetVcoCalDataTx(calData);
 *
 *  SpiritCmdStrobeReady();
 *  SpiritCalibrationVco(S_DISABLE);
 *
 * @endcode
 *
 * Similar operations can be done for the RCO calibrator.
 *
