I'm sorry I'd made that mistake while typing the program on the forum post. The original code is just like the as follows

cs=0; 
wr=0; 
adc=0x08; 
wr=1; 
cs=1; 
adc=0xFF; 

 

and..

while(intr==1);
cs=0;

rd=0;
value=adc;
cnd(value);
rd=1;
cs=1;

 

I'm sorry for the error.

In spite of this code, I get an all pins high output.
What could be the reason?
