The pull-up resistor should be connected to the same supply voltage as the USB-Blaster, MasterBlaster (V
ByteBlaster II, or ByteBlasterMV cable.
Connect the nCONFIG and MSEL[3..0] pins to support a non-JTAG configuration scheme. If only JTAG
configuration is used, connect the nCONFIG pin to V
and DATA[0] to either high or low, whichever is convenient on your board.
Pin 6 of the header is a V
V
pin is a no connect. In the USB-Blaster and ByteBlaster II, this pin is connected to nCE when it is used for AS
programming, otherwise it is a no connect.
nCE must be connected to GND or driven low for successful JTAG configuration.
The nCEO pin can be left unconnected or used as a user I/O pin when it does not feed other device’s nCE pin.
Power up the ByteBlaster II, USB Blaster, or ByteBlasterMV cable’s V
programmers must switch to 2.5V. Pin 4 of the header is a V
MasterBlaster cable can receive power from either 5.0- or 3.3-V circuit boards, DC power supply, or 5.0 V from the
USB cable. Refer to the MasterBlaster Serial/USB Communiations Cable Data Sheet for this value.
