The mode select pins, M[2:0], are sampled when the
FPGA’s INIT_B output goes High and must be at defined
logic levels during this time. After configuration, when the
FPGA’s DONE output goes High, the mode pins are avail-
able as full-featured user-I/O pins.
enable pull-up resistors on all user-I/O pins or High to dis-
able the pull-up resistors. The HSWAP control must remain
at a constant logic level throughout FPGA configuration.
After configuration, when the FPGA’s DONE output goes
High, the HSWAP pin is available as full-featured user-I/O
pin and is powered by the VCCO_0 supply.

Voltage Compatibility
FPGA’s I/O Bank 2, supplied by the VCCO_2 supply input.
The VCCO_2 voltage can be 3.3V, 2.5V, or 1.8V to match
the requirements of the external host, ideally 2.5V. Using
3.3V or 1.8V requires additional design considerations as
the DONE and PROG_B pins are powered by the FPGA’s
2.5V V
tion of Spartan-3 FPGAs for additional information.
Daisy-Chaining
If the application requires multiple FPGAs with different con-
figurations, then configure the FPGAs using a daisy chain,
as
(M[2:0] = <1:1:1>) for all FPGAs in the daisy-chain. After
the lead FPGA is filled with its configuration data, the lead
FPGA passes configuration data via its DOUT output pin to
the next FPGA on the falling CCLK edge.
