7.2.2.3.2. Using Multiple Configuration Data

To configure multiple Cyclone® 10 GX devices in a chain using multiple configuration data, connect the devices to the external host as shown in the following figure.

Note: By default, the nCEO pin is disabled in the Quartus® Prime Pro Edition software. For the multi-device configuration chain, you must enable the nCEO pin in the Quartus® Prime Pro Edition software. Otherwise, device configuration could fail.

After a device completes configuration, its nCEO pin is released low to activate the nCE pin of the next device in the chain. Configuration automatically begins for the second device in one clock cycle.
