This is to ensure that the DATA0 and DCLK pins are not left floating after configuration.For example, if the design also uses a configuration device, the pull-up resistors on the DATA0 and DCLK pins arenot necessary.(3) Pin 6 of the header is a V IO reference voltage for the MasterBlaster output driver. V IO should match the targetdevice’s V CCIO . This is a no-connect pin for the ByteBlasterMV header.(4) You should not attempt configuration with a download cable while a configuration device is connected to a Stratixor Stratix GX device. Instead, you should either remove the configuration device from its socket when using thedownload cable or place a switch on the five common signals between the download cable and the configurationdevice. Remove the download cable when configuring with a configuration device.(5) If nINIT_CONF is not used, nCONFIG must be pulled to V CC either directly or through a resistor.(6) If external pull-ups are used on CONF_DONE and nSTATUS pins, they should always be 10 kΩ resistors. You can usethe internal pull-ups of the configuration device only if the CONF_DONE and nSTATUS signals are pulled-up to 3.3 Vor 2.5 V (not 1.8 V or 1.5 V).fFor more information on how to use the MasterBlaster or ByteBlasterMVcables, see the following documents:■■■■USB-Blaster USB Port Download Cable Data SheetMasterBlaster Serial/USB Communications Cable Data SheetByteBlasterMV Parallel Port Download Cable Data SheetByteBlaster II Parallel Port Download Cable Data SheetAltera Corporation 11–17July 2005 Stratix Device Handbook, Volume 2
