Reading Data line from ADSP - 2181 EZ kit

Hai all,

Is there any mechanism to read the data on the data pins of ADSP-2181 EZ kit lite (D0-D23) like how we can read using programmable flags ?(Which can be made either input or output ports).

In Programmable flags we can do like this

      AX0=0xff; //configure programmable flags for o/p
      dm(Prog_Flag_Comp_Sel_Ctrl)=AX0;

      AY1=0x61; //o/p 61 will appear on PF lines
      dm(Prog_Flag_Data)= AY1;
       
 

In the same way is it possible to read from D0-D23 lines ?
Wheather Data tht has been put is persistant ?

If not so wheather we have to make what all conditions  we need to maintain ? RD(bar) or WR(BAR)  et.c

IS so how to do tht ?

So tht the o/p is made available to outside world.
Bye
