We are connecting two DDR3 SDRAM ICs to a Cyclone V 5CEFA9F31. Our application only requires one ODT signal. However, there are two hard memory controller pins (T_ODT_0 and T_ODT_1). Can we use either one, or do we need to use a specific pin when we only use one signal?

The dramodt section on pages 4-45 and 4-46 in the External Memory Interface Handbook Volume 3 seems to indicate that any combination of ODT[0] and ODT[1] can be configured to be asserted for CS0 and CS1. Is that correct?

No one has been able to help me with this question yet. Is there anyone who can help me with this ODT pin question?
