  * @version 3.2.2
  * @date    08-July-2015
 * @brief   Configuration and management of the common features of SPIRIT packets.
  * 
 * @details
 *
 * This module provides all the common functions and definitions used by the
 * packets modules.
 * Here are also defined all the generic enumeration types that are redefined
 * in the specific packets modules, but every enumeration value is referred
 * to this module. So the user who wants to configure the preamble of a Basic,
 * or a STack packet has to use the enumeration values defined here.
 *
 * <b>Example:</b>
 * @code
 *
 *   ...
 *
 *   SpiritPktBasicSetPreambleLength(PKT_PREAMBLE_LENGTH_18BYTES);
 *
 *   ...
 *
 * @endcode
 *
 * @note Is recommended for the user to not use these API directly
 * importing this module in his application.
 *
