What language are you using?
The PORTB interrupt pin will be exactly what you want for 1 interrupt (RB0)
PORTB bit 4-7 can be configured as interrupt on change sources for more than a 1 pin interrupt.

Thanx for your reply...
I am using c language and the compiler is MicroC... can you give me a sample c code for interrupt mechanism....
Why can't you write your own? It's not hard. It's about 10-20 to set up, not a lot of work. If you do it on your own, you will also understand how the code works.
thanx..i will write it on my own an check it...if there is any problem i will contact you....
