The configuration mode jumpers determine which configuration mode the FPGA uses
when power is first applied, or whenever the PROG button is pressed.
The DONE pin LED lights when the FPGA successfully finishes configuration.
Pressing the PROG button forces the FPGA to restart its configuration process.
The 4 Mbit Xilinx Platform Flash PROM provides easy, JTAG-programmable configuration
storage for the FPGA. The FPGA configures from the Platform Flash using Master Serial
mode.
The 64-macrocell XC2C64A CoolRunner II CPLD provides additional programming
capabilities and flexibility when using the BPI Up, BPI Down, or MultiBoot configuration
modes and loading the FPGA from the StrataFlash parallel Flash PROM. The CPLD is user-
programmable.

mode. Inserting a jumper grounds the associated mode pin. Insert or remove individual
jumpers to select the FPGA's configuration mode and associated configuration memory
source.
