Configuring Cyclone II DevicesSingle Device JTAG ConfigurationDuring JTAG configuration, you can use the USB-Blaster, MasterBlaster,ByteBlaster II, or ByteBlasterMV download cable to download data to thedevice. Configuring Cyclone II devices through a cable is similar toprogramming devices in system. Figure 13–22 shows JTAG configurationof a single Cyclone II device using a download cable.Figure 13–22.

If only JTAGconfiguration is used, connect the nCONFIG pin to V CC , and the MSEL[1..0] pins to ground. In addition, pull DCLKand DATA0 to either high or low, whichever is convenient on your board.(3) Pin 6 of the header is a V IO reference voltage for the MasterBlaster output driver. V IO should match the device’sV CCIO . Refer to the MasterBlaster Serial/USB Communications Cable Data Sheet for this value. In the ByteBlasterMV,this pin is a no connect. In the USB-Blaster and ByteBlaster II, this pin is connected to nCE when it is used for ASprogramming, otherwise it is a no connect.(4) nCE must be connected to GND or driven low for successful JTAG configuration.(5) The nCEO pin can be left unconnected or used as a user I/O pin when it does not feed other device’s nCE pin.GNDTo configure a single device in a JTAG chain, the programming softwareplaces all other devices in BYPASS mode. In BYPASS mode, Cyclone IIdevices pass programming data from the TDI pin to the TDO pin througha single bypass register without being affected internally.
