You should connect the pull-up resistor to the same supply voltage as the MasterBlaster (VIO pin) or ByteBlasterMV
cable.
The pull-up resistors on the DATA0 and DCLK pins are only needed if the download cable is the only configuration
scheme used on the board. This is to ensure that the DATA0 and DCLK pins are not left floating after configuration.
For example, if the design also uses a configuration device, the pull-up resistors on the DATA0 and DCLK pins are
not necessary.

If you are using a download cable to configure device(s) on a board that
also has configuration devices, you should electrically isolate the
configuration devices from the target device(s) and cable. One way to
isolate the configuration devices is to add logic, such as a multiplexer, that
can select between the configuration devices and the cable. The
multiplexer device should allow bidirectional transfers on the nSTATUS
and CONF_DONE signals. Another option is to add switches to the five
common signals (CONF_DONE, nSTATUS, DCLK, nCONFIG, and DATA0)
between the cable and the configuration devices. The last option is to
remove the configuration devices from the board when configuring with
the cable.
