Chapter 1: VC709 Evaluation Board Features
Configuration Mode and Upper Linear Flash Address Switch (SW11)
[Figure
FPGA Configuration Mode: The mode signals FPGA_M2, _M1, and _M0 are connected to
FPGA U1 pins AJ10, AK10, and AL10, respectively. Configuration mode is used at
power-up or when the PROG pushbutton is pressed.
Linear BPI Flash Upper Addresses: DIP switch SW11 positions 1 and 2 control the setting
of address bits FLASH_A25 and FLASH_A24.

Power On/Off Slide Switch SW12
[Figure
The VC709 board power switch is SW12. Sliding the switch actuator from the Off to On
position applies 12V power from J18, a 6-pin mini-fit connector. Green LED DS16
illuminates when the VC709 board 12V power is on. See
details on the onboard power system.
The VC709 evaluation kit provides the adapter cable shown in
the VC709 board from the ATX power supply 4-pin peripheral connector. The Xilinx part
number for this cable is 2600304, and is equivalent to Sourcegate Technologies part number
AZCBL-WH-1109-RA4.

Caution!
Do NOT plug a PC ATX power supply 6-pin connector into J18 on the VC709 board.
The ATX 6-pin connector has a different pinout than J18. Connecting an ATX 6-pin connector into
J18 damages the VC709 board and voids the board warranty.
