IBUFDS_DIFF_OUT_INTERMDISABLE

The IBUFDS_DIFF_OUT_INTERMDISABLE primitive shown in This Figure is available in the HR I/O banks. It has complementary differential outputs and an INTERMDISABLE port that can be used to manually disable the optional on-die receiver termination features (uncalibrated). See Uncalibrated Input Termination in I/O Banks for more details.

TIP: The IBUFDISABLE feature is not supported with this primitive in the UltraScale architecture.

If the I/O is using any on-die receiver termination features (uncalibrated), this primitive disables the termination legs whenever the INTERMDISABLE signal is asserted High.
