Example implies that V CCO , V CCJ , and/or V CCAUX for various devices in the JTAG chain are set to the same voltage.
Attach the following 2-mm connector pins to digital ground: 3, 5, 7, 9, and 11.
The cable uses an open-drain driver to control the pseudo ground (PGND) signal — an external pull-up resistor is required.
Assumes that the multiplexor supply voltages pins are connected to V CCAUX .
Pin 13 is grounded on legacy Xilinx USB cables (models DLC9, DLC9G and DLC9LP), and Parallel Cable IV (model DLC7). These cables
need to be manually detached from the 2-mm connector to allow the primary configuration source to have access to the JTAG chain.
