JTAG/Configuration Chain Connection
Connect the JTAG pins of the device to the download cable header correctly. If you
have more than one device in the chain, connect the TDO pin of a device to the TDI pin
of the next device in the chain.
All I/O inputs must maintain a maximum AC voltage of 4.1 V. Because JTAG pins do
not have the internal PCI clamping diodes to prevent voltage overshoot when using

The operating voltage supplied to the Altera download cable by the target board
through the 10-pin header determines the I/O voltage level of the download cable.
The JTAG pins for all Cyclone III devices reside in Bank 1 and their I/O standard
support is controlled by the V
