ID:169047 Pin <name> is using bus-hold with a differential I/O standard. Using bus-hold with differential pins is not recommended because the common mode voltage will shift. This may cause signal integrity issues at high speed. Performance is not guaranteed for this configuration.

CAUSE: You turned on both the Enable Bus-Hold Circuitry logic option and a differential I/O standard for the specified pin. Performance is not guaranteed for this configuration.

ACTION: Modify the settings so that you enable only one of these assignments for the pin.
