CAUSE: The Fitter cannot reserve the specified pin because it has an illegal setting. The RESERVE_PIN parameter, assigned to the specified pin in the Quartus Prime Settings File (.qsf) file, has a setting other than As input pin tri-stated, As output pin driving ground, As output pin driving an unspecified signal, or As output pin driving VCC. This message can occur when you edit the Quartus Prime Settings File (.qsf) manually to create assignments. Altera recommends that you not directly edit the QSF. Instead, you should reserve a pin using the Assignment Editor.
ACTION: Reserve the pin with a legal setting.
