22.214.171.124.2. Using Multiple Configuration Data
To configure multiple Intel® Cyclone® 10 GX devices in a chain using multiple configuration data, connect the devices to an external host as shown in the following figure.
When a master device completes configuration, its nCEO pin is released low to activate the nCE pin of the next device (for example, a slave device) in the chain. Configuration automatically begins for the slave device in one clock cycle.
Note that after the master device receives the configuration bitstream and asserts its nCEO pin low, it will no longer read data even when DCLK is toggling. Once the slave device has received the complete configuration data from the host controller, the master device will enter user mode.
