Could some one explain some thing in this schematic please :)

Im very new to FPGA's and am using this attached schematic to crib from. every thing makes sense apart from the following FPGA pins pins 26,81 held high to 1.2v pins 27,80 held to ground ...

I want to configure this device using just JTAG for quick testing

Why not use MPSSE mode for JTAG programming directly?

You could wire the FTDI to the JTAG chain and then program either the FPGA or the EPCS device.

You could add a multiplexer, or tri-state the FTDI pins, and still be able to use the external JTAG connector.

Cheers,
