18.104.22.168.1. Controlling EPCQ-L Devices
During configuration, Intel® Arria® 10 devices enable the EPCQ-L device by driving its nCSO output pin low, which connects to the chip select (nCS) pin of the EPCQ-L device. Intel® Arria® 10 devices use the DCLK and ASDO pins to send operation commands and read address signals to the EPCQ-L device. The EPCQ-L device provides data on its serial data output (DATA) pin, which connects to the AS_DATA input of the Intel® Arria® 10 devices.
