I have read http://www.keil.com/forum/1854/how-to-use-extern-sbit-declare/
My problem is same. Using "extern sbit" works as mentioned in above post for small project.
My project has more then 10 files.
Now same solution do not work.
man i realy like your code. but when you fix the small bug error you send it to us. we need more good examples like it.
Thanks a lot for guidance. Unfortunately, actual code is a very large code. I had generated this sample code. As soon as I realized mistake, I erased it. Sorry for that.
Thanks again
