PROG Push Button R
PROG Push Button
The PROG push button, shown in Figure 4-2, page 26 , forces the FPGA to reconfigure from
the selected configuration memory source. Press and release this button to restart the
FPGA configuration process at any time.
DONE Pin LED
The DONE pin LED, shown in Figure 4-2, page 26 , lights whenever the FPGA is
successfully configured. If this LED is not lit, then the FPGA is not configured.
