This is to ensure that DATA0 and DCLK are not left floating after configuration. For example, ifyou are also using a configuration device, the pull-up resistors on DATA0 and DCLK are not needed.(3) Pin 6 of the header is a VIO reference voltage for the MasterBlaster output driver. VIO should match the device’sV CCIO . Refer to the MasterBlaster Serial/USB Communications Cable Data Sheet for this value. In theByteBlasterMV, this pin is a no connect. In the USB Blaster and ByteBlaster II, this pin is connected to nCE when itis used for Active Serial programming, otherwise it is a no connect.Altera Corporation 7–31August 2005 Configuration Handbook, Volume 1
