Initialization Indicator. Active
Low. Goes Low at start of
configuration during Initialization
memory clearing process.
Released at end of memory
clearing, when mode select pins
are sampled. In daisy-chain
applications, this signal requires
an external 4.7 kΩ pull-up resistor
to VCCO_2.
FPGA Configuration Done. Low
during configuration. Goes High
when FPGA successfully
completes configuration.
Requires external 330 Ω pull-up
resistor to 2.5V.
Program FPGA. Active Low.
When asserted Low for 500 ns or
longer, forces the FPGA to restart
its configuration process by
clearing configuration memory
and resetting the DONE and
INIT_B pins once PROG_B
returns High. Recommend
external 4.7 kΩ pull-up resistor to
2.5V. Internal pull-up value may
be weaker (see
driving externally with a 3.3V
output, use an open-drain or
open-collector driver or use a
current limiting series resistor.
