Notes to
(1) Connect these pull-up resistors to the V
(2) Connect the nCONFIG and MSEL[3..0] pins to support a non-JTAG configuration scheme. If you only use a JTAG
(3) Pin 6 of the header is a V
(4) The nCE pin must be connected to GND or driven low for successful JTAG configuration.
(5) The nCEO pin is left unconnected or used as a user I/O pin when it does not feed the nCE pin of another device.
(6) Power up the V

configuration, connect the nCONFIG pin to logic high and the MSEL[3..0] pins to ground. In addition, pull DCLK
and DATA[0] either high or low, whichever is convenient on your board.
For this value, refer to the
