JTAG instructions have precedence over any other configuration modes. Therefore,
JTAG configuration can take place without waiting for other configuration modes to
complete. For example, if you attempt JTAG configuration in Cyclone IV devices
during PS configuration, PS configuration terminates and JTAG configuration begins.
If the MSEL pins are set to AS mode, the Cyclone IV device does not output a DCLK
signal when JTAG configuration takes place.
The four required pins for a device operating in JTAG mode are TDI, TDO, TMS, and
TCK. All the JTAG input pins are powered by the V
I/O standard only. All user I/O pins are tri-stated during JTAG configuration.

You can download data to the device through the USB-Blaster, MasterBlaster,
ByteBlaster II, or ByteBlasterMV download cable, or the EthernetBlaster
communications cable during JTAG configuration. Configuring devices with a cable is
similar to programming devices in-system.
