I have program a DS1302 & At89c51 C code using keil and compile a hex file, den i load the hex file using flip.

Everything was fine,just that the lCD show 85 : 85 : 85 for the time and the time did not run at all.  What can be the problem??

Correct me if there is something that im wrong or i need to change. Thx!

 

 

Below is the code
