Feature Descriptions
For external measurements an XADC header (J19) is provided. This header can be used to provide analog inputs to the FPGA's dedicated VP/VN channel, and to the VAUXP[0]/VAUXN[0],
VAUXP[8]/VAUXN[8] auxiliary analog input channels. Simultaneous sampling of Channel 0 and Channel 8 is supported.
A user-provided analog signal multiplexer card can be used to sample additional external analog inputs using the 4 GPIO pins available on the XADC header as multiplexer address lines. Figure1-35 shows the XADC header connections.

Configuration Options
The FPGA on the VC707 board can be configured by the following methods:??
Master BPI (uses the Linear BPI Flash).
JTAG (uses the USB-to-JTAG Bridge or Download cable). See USB JTAG for moreinformation
See 7SeriesFPGAs Configuration UserGuide (UG470) [Ref3] for further details on configuration modes.
The method used to configure the FPGA is controlled by the mode pin (M2, M1, M0) settings selected through DIP switch SW11. Table1-34 lists the supported mode switch settings.Table 1-34:

The mode pins settings on SW11 determine if the Linear BPI Flash is used for configuring the FPGA. DIP switch SW11 also provides the upper two address bits for the Linear BPI Flash and can be used to select one of multiple stored configuration bitstreams. Figure1-37 shows the connectivity between the onboard nonvolatile Flash devices used for configuration and the FPGA.
To obtain the fastest configuration speed an external 80MHz oscillator is wired to the EMCCLK pin of the FPGA. This allows users to create bitstreams that configure the FPGA over the 16-bit datapath from the Linear BPI Flash memory at a maximum synchronous read rate of 80MHz.
