In 16-bit mode, you have to use the hardware FC bit (controlled by the CPLD on the DSK C5402 board) to request secondary communications, and thus correctly (and completely) configure the AD50. Did you do that? Not too long ago I posted on this group an asm. language source code example for configuring the AD50 on the C5402. This shows how to use the FC line for 16-bit configuration. It should be in the archives; I think around early October.
