7.2.1.5.1. 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.

Note: If you wish to gain control of the EPCQ-L pins, hold the nCONFIG pin low and pull the nCE pin high. This causes the device to reset and tri-state the AS configuration pins.
