Passive Serial ConfigurationIn addition, because the nSTATUS pins are tied together, the entire chainhalts configuration if any device detects an error. The Auto-restartconfiguration after error option does not affect the configuration cyclebecause you must manually restart configuration in the Quartus IIsoftware when an error occurs.Figure 7–28 shows how to configure multiple Stratix II or Stratix II GXdevices with a download cable.Figure 7–28.

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 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.7–70 Altera CorporationStratix II Device Handbook, Volume 2 May 2007
