button (S3).

FPGA Programming over External USB-Blaster

The JTAG programming header provides another method for configuring the FPGA

using an external USB-Blaster device with the Quartus II Programmer running on a

PC. The external USB-Blaster connects to the board through the JTAG connector (J5).

Both FPGAs and the MAX II devices are always in the JTAG chain.
