 * @brief   Management of SPIRIT Commands.
  *
 * @details
 *
 * In this module can be found all the API used to strobe commands to
 * Spirit.
 * Every command strobe is an SPI transaction with a specific command code.
 *
 * <b>Example:</b>
 * @code
 *   ...
 *
 *   SpiritCmdStrobeRx();
 *
 *   ...
 * @endcode
 *
