I have next assume.

Maybe your device sets "endofpacket" signal before ending of transferring.

In this case disable bit REEN or WEEN, it depends on a direction or transferring.

Other case there is an increment of write address. Disable WCON in this case.

I hope it helps you http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif
