V IO should match the device’sV CCIO . Refer to the MasterBlaster Serial/USB Communications Cable Data Sheet for this value. In the ByteBlasterMVcable, this pin is a no connect. In the USB Blaster and ByteBlaster II cables, this pin is connected to nCE when it isused for active serial programming, otherwise it is a no connect.(3) You should not attempt configuration with a download cable while a configuration device is connected to a Stratix IIor Stratix II 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.(4) The nINIT_CONF pin (available on enhanced configuration devices and EPC2 devices only) has an internal pull-upresistor that is always active. This means an external pull-up resistor should not be used on thenINIT_CONF-nCONFIG line. The nINIT_CONF pin does not need to be connected if its functionality is not used.(5) The enhanced configuration devices’ and EPC2 devices’ OE and nCS pins have internal programmable pull-upresistors. If internal pull-up resistors are used, external pull-up resistors should not be used on these pins. Theinternal pull-up resistors are used by default in the Quartus II software. To turn off the internal pull-up resistors,check the Disable nCS and OE pull-up resistors on configuration device option when generating programmingfiles.fFor more information on how to use the USB Blaster, MasterBlaster,ByteBlaster II or ByteBlasterMV cables, refer to the following data sheets:■■■■USB Blaster USB Port Download Cable Data SheetMasterBlaster Serial/USB Communications Cable Data SheetByteBlaster II Parallel Port Download Cable Data SheetByteBlasterMV Parallel Port Download Cable Data Sheet7–72 Altera CorporationStratix II Device Handbook, Volume 2 May 2007
