I have been given a GPIB PCB which uses a TNT5002 chip. However, I am having trouble reading the registers using a TI Omap-138 CPU with the board attached to the CPU's EMIFA bus interface.
In particular, I believe that the PCB I have does not use HWORD properly. Unfortunately, the information in the TNT5002 Tech Ref is vague and I have not been able to find anything on the NI site or elsewhere on the internet which shows the TNT5002 correclty wired up. Apparently there was once an example schematic but it no longer exists anywhere.
