Hello gopal,
               In VIC, we can configure the interrupts according to the 
priority.
Maximum we can configure 16 interrupts.It will vary from 0 to 16.
For ecah interrupt,they already defined some predined address.


If you write the code like this means,
        VICVectAddr1 = (unsigned)EXTINTVectoredIRQ; 

This ISR function will be call from the Predefined address.


It means we configure certain tasks,if the interrupt is rised.






Hello
What is the purpose or use of this register
Vector Address Register. 
When an IRQ interrupt occurs, the IRQ service VICVectAddr routine can
read this register and jump to the value read.
Is it used for OS priority scheduling purpose or for some other reasons
