I use Mod5234 to accept data via external data bus and send them via ethernet.
How can I get data from 16 bits external data bus?Where can I find the file defining address map for peripheral devices?

Getting data from a 16-bit bus is very similar to the 8-bit bus. You simply change the PS bits of the CSCR register for the chip select and connect the 8 extra data bus signals. The memory map for your module is found in this document:
C:\Nburn\docs\platform\Mod5234.pdf
You can use any section of memory that is declared "Unused"
