 * This note defines an application program interface (API) for    *
 * the use of the FLX PCIe I/O card in the ATLAS read-out system.  *
 * The intention of the API is to satisfy the needs of simple      *
 * test programs as well as the requirements of the                *
 * FelixApplication.                                               *
