C2000-Gang烧录器提供的dll使用问题

[DllImport("C2000-Gang.dll", EntryPoint = "C2000GANG_Interactive_WriteWords_to_FLASH", ExactSpelling = false, CallingConvention = CallingConvention.StdCall)]
public static unsafe extern Int32 Interactive_WriteWords_to_FLASH( Int32 addr, Int32 size, Int16* data);

C#调用这个函数的时候，int16* data这个参数怎么来？
