ID:53008 Port <name> can be used only when the <ctrl> address is registered

CAUSE: You specified an altdpram instance with a rden or rdaddressstall or wraddressstall port, but the port can be used only when a read/write address is registered. This warning usually occurs when you instantiate a megafunction directly in a text file rather than using the MegaWizard Plug-In Manager .

ACTION: Modify the design to use the a registered read/write address or do not use the rden or rdaddressstall or wraddressstall port. To avoid receiving this message in the future, Intel recommends using the MegaWizard Plug-In Manager.
