Wood Walls Framed for Fire

Since FRTW studs are allowed in wall assemblies that are otherwise defined as non-combustible, building and truss designers often confront the question does a joint between the wall and the roof or floor assembly mean that those elements of the building also require noncombustible material, like FRTW? To answer this, we need to study the IBC

Question: 

Would you please inform me of the specified requirements of the size and the amount of nail attachments from the truss to the top plate?
