Passive Serial Configuration
In addition, because the nSTATUS pins are tied together, the entire chain
halts configuration if any device detects an error. The Auto-restart
configuration after error option does not affect the configuration cycle
because you must manually restart configuration in the Quartus II
software when an error occurs.
Figure 7–28 shows how to configure multiple Stratix II or Stratix II GX
devices with a download cable.

Notes to Figure 7–28:
(1) The pull-up resistor should be connected to the same supply voltage as the USB Blaster, MasterBlaster (V_IO pin),
ByteBlaster II or ByteBlasterMV cable.
(2) The pull-up resistors on DATA0 and DCLK are only needed if the download cable is the only configuration scheme
used on your board. This is to ensure that DATA0 and DCLK are not left floating after configuration. For example, if
you 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’s
V_CCIO. Refer to the MasterBlaster Serial/USB Communications Cable User Guide for this value. In the ByteBlasterMV
cable, this pin is a no connect. In the USB Blaster and ByteBlaster II cables, this pin is connected to nCE when it is
used for active serial programming, otherwise it is a no connect.
