Connect the pull-up
resistors to V

at a
3.0- or 3.3-V power supply.
The resistor value can vary
from 1 kΩ to 10 kΩ. Perform
signal integrity analysis to
select the resistor value for
your setup.
For more information, refer to
the MSEL pin settings.
Instantiate SFL in your
design to form a bridge
between the EPCS and the
10-pin header.
Use the CLKUSR pin to supply
the external clock source to drive
DCLK during configuration.
