Spartan-3 FPGA Family: Functional Description
when operating in the User mode. This is accomplished by
setting the Persist option to Yes.
Multiple FPGAs can be configured using the Slave Parallel
mode and can be made to start-up simultaneously.

There are two ways to use the DONE line. First, one may set the BitGen option DriveDone to "Yes" only for the last FPGA
to be configured in the chain shown above (or for the single FPGA as may be the case). This enables the DONE pin to drive
High; thus, no pull-up resistor is necessary. DriveDone is set to "No" for the remaining FPGAs in the chain. Second,
DriveDone can be set to "No" for all FPGAs. Then all DONE lines are open-drain and require the pull-up resistor shown in
grey. In most cases, a value between 3.3KΩ to 4.7KΩ is sufficient. However, when using DONE synchronously with a long
chain of FPGAs, cumulative capacitance may necessitate lower resistor values (e.g. down to 330Ω) in order to ensure a rise
time within one clock cycle.
If the FPGAs use different configuration data files, configure them in sequence by first asserting the CS_B of one FPGA then
asserting the CS_B of the other FPGA.

tiple devices in this way, wire the individual CCLK, Data,
RDWR_B, and BUSY pins of all the devices in parallel. The
individual devices are loaded separately by deasserting the
CS_B pin of each device in turn and writing the appropriate
data.
