If only JTAGconfiguration is used, connect nCONFIG to V CC , and MSEL[1..0] to ground. Pull DCLK 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 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.(4) nCE must be connected to GND or driven low for successful JTAG configuration.ISP of Serial Configuration DeviceIn the second stage, the serial flash loader design in the master Cyclone IIdevice allows you to write the configuration data for the device chain intothe serial configuration device by using the Cyclone II JTAG interface.The JTAG interface sends the programming data for the serialconfiguration device to the Cyclone II device first. The Cyclone II devicethen uses the ASMI pins to transmit the data to the serial configurationdevice.Altera Corporation 13–63February 2007 Cyclone II Device Handbook, Volume 1
