microcontroller... 

 
How we can use it for two interfacing on single port..

You face some problems describing exactly what problem you are
facing.&lt;/p&gt;

&lt;p&gt;
Exactly what problem do you have? Exactly what code doesn&amp;#39;t do
what you expect it to do? What happens, and what did you expect to
happen?&lt;/p&gt;

&lt;p&gt;
There are lots of sample code available that shows how to toggle a
single pin on a port without changing the state of the other 31 bits.
Have you looked? The user manual for the processor also discusses
this situation. Have you looked?&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
