Altera Active Serial Memory Interface - Manual (Page 2)

This figure shows that you can use the Altera ASMI Parallel IP core to access the general purpose memory
portion of the EPCS/EPCQ/EPCQ-L devices through the supported Altera devices.
Caution: Altera recommends you to be cautious when accessing the configuration memory in the EPCS/
EPCQ/EPCQ-L device to avoid corrupting the configuration bits.
