You can have multiple devices that contain the same configuration data in your system.

Figure 90. Multiple Device PS Configuration When Both Devices Receive the Same Configuration Data

The nCE pins of the device in the chain are connected to GND, allowing configuration for these devices to begin and end at the same time. nCONFIG, nSTATUS, DCLK, DATA[0], and CONF_DONE configuration pins are connected to every device in the chain.

To ensure signal integrity and prevent clock skew problems, configuration signals may require buffering. Ensure that the DCLK and DATA lines are buffered.
