XC4000 Series Field Programmable Gate Arrays
Slave Serial Mode
In Slave Serial mode, an external signal drives the CCLK
input of the FPGA. The serial configuration bitstream must
be available at the DIN input of the lead FPGA a short setup
time before each rising CCLK edge.
The lead FPGA then presents the preamble data—and all
data that overflows 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 FPGA in the daisy chain accepts data on the sub-

Series device in Slave Serial mode should be connected as
shown in the third device from the left.
Slave Serial mode is selected by a <111> on the mode pins
(M2, M1, M0). Slave Serial is the default mode if the mode
pins are left unconnected, as they have weak pull-up resis-
tors during configuration.
