Is DCLK a dual-purpose pin in Stratix V, Arria V and Cyclone V devices?

Description

No, DCLK is not a dual-purpose pin in the Stratix® V, Arria® V and Cyclone® V device familes, so it is not possible to manually assign a user signal to this pin in the Quartus® II design software.

 
However, if using the ALTASMI_PARALLEL megafunction or the EPCS Controller component in QSys, DCLK will be accessible by these functions in user mode, to faciliate access to an EPCS or EPCQ device.
