The input buffer can be dynamically disabled using a control signal from the interconnect logic to drive the IBUFDISABLE port of the buffer primitive. Disabling the input buffer can help reduce power consumption when the input bus is idle.

The IBUF_IBUFDISABLE, IBUFDS_IBUFDISABLE, and IBUFDS_DIFF_OUT_IBUFDISABLE primitives can all be used in the HD I/O. See SelectIO Interface Primitives for more details on these primitives.
