FPGA Programming over External USB-Blaster
The JTAG chain header provides another method for configuring the FPGA using an
external USB-Blaster device with the Quartus II Programmer running on a PC. To
prevent contention between the JTAG masters, the embedded USB-Blaster is
automatically disabled when you connect an external USB-Blaster to the JTAG chain
through the JTAG chain header.
