7.2.3.2.3. Using One Configuration Data

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

Note: If you are using the FPP x8 configuration mode, use DATA[7..0] pins. If you are using FPP x16 configuration mode, use DATA[15..0] pins. If you are using FPP x32 configuration mode, use DATA[31..0] pins.
Note: By default, the nCEO pin is disabled in the Quartus® Prime Pro Edition software. For multi-device configuration chain, you must enable the nCEO pin in the Quartus® Prime Pro Edition software. Otherwise, device configuration could fail.

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.
