 * @brief     Initialization program for LCD DOGM162. Qsys uses Altera
 *            LCD component "altera_avalon_lcd_16207".
 * @remark    This initialization function extends the standard
 *            initialization by DOGM162 specific initialization. This
 *            function has to be called before the display can be used.
 *************************************************************************
 * @par History:
 *  @details  V2.0.2 06.11.2014 Kossmann
 *            - moved clear, set-position functionality into
 *              auxilaryFunctions.c because stream not available here
 *  @details  V2.0.1 06.11.2014 Riedel
 *            - Created defines for init-codes and moved to header
 *  @details  V2.0.0 Ferdinand Englberger
 *            - comments in english
 *            - Remove all functions, but initialization function
 *            - uses component register interface, instead of own access
 *              function.
 *            - uses a base parameter to identify lcd.
 *  @details  V1.1 25.06.2012 Johann Mayr
 *            - Initial version
 *  @details  V1.0 20.12.2011 Johann Mayr
