ID:169069 Following <number> pins have nothing, GND, or VCC driving datain port -- changes to this connectivity may change fitting results

CAUSE: The specified pins either have nothing, GND, or VCC driving the datain port. If you modify this setting, additional pin placement restrictions such as simultaneously switching outputs may be necessary and may lead to a change in the fitting results.

ACTION: If you do not intend to connect these pins, no action is required. Otherwise, modify the design to reflect the required connectivity.
