Slave Serial Mode
In Slave Serial mode, an external signal drives the CCLK
input(s) of the FPGA(s). The serial configuration bitstream
must be available at the DIN input of the lead FPGA a short
set-up time before each rising CCLK edge. The lead device
then presents the preamble data (and all data that over-

flows the lead device) on its DOUT pin. There is an internal
delay of 0.5 CCLK periods, which means that DOUT
changes on the falling CCLK edge, and the next device in
the daisy-chain accepts data on the subsequent rising
CCLK edge.
