Functional Description
Daisy-Chaining
If the application requires multiple FPGAs with different con-
figurations, then configure the FPGAs using a daisy chain,
as shown in
Programming Support
For successful daisy-chaining, the DONE_cycle configura-
tion option must be set to cycle 5 or sooner. The default
cycle is 4. See

third-party gang programmers. Consult your specific SPI
Flash vendor for recommended production programming
solutions.
In-system programming support is available from some
third-party PROM programmers using a socket adapter with
attached wires. To gain access to the SPI Flash signals,

serial Flash PROM is supported in Stepping 1 and later

Flash mode (M[2:0] = <0:0:1>) for the FPGA connected to
the Platform Flash PROM and Slave Serial mode
(M[2:0] = <1:1:1>) for all other FPGAs in the daisy-chain.
After the master FPGA—the FPGA on the left in the dia-
gram—finishes loading its configuration data from the SPI
Flash PROM, the master device uses its DOUT output pin
to supply data to the next device in the daisy-chain, on the
falling CCLK edge.

driver. This action places all FPGA I/O pins, including those
attached to the SPI Flash, in high-impedance (Hi-Z). If the
