You can download data to the device on the PCB through the USB-Blaster,
MasterBlaster, ByteBlaster II, ByteBlasterMV download cable, and Ethernet-Blaster
communications cable during JTAG configuration. Configuring devices using a cable
is similar to programming devices in-system.
JTAG configuration of a single Cyclone III device family.
