Very Urgent :VIC in ARM Cortex R4

Hi all,

It was nice experience working with NXP with my favorite S32K1XX series having ARM Cotex M-4 and M-0+.

 Now i switched to BCM895XX series with ARM Cotex R-4 having VIC for interrupt contolling.

 I am working with controller having ARM cortex R-4 , which supports VIC (PL190) for interrupt controlling. I searched a lot but not satisfied. Now i come here again.

I have few questions:

1- Does VICIRQSTATUS register gives the currently IRQ interrupt servicing by processor.

2. Which status gives the VICRAWINTR register. 

3. I want the current executing interrupt source number( decimal number out of 32 interrupt source ) at run time . I am     only getting the status bit being set in STATUS register . Also I am not getting any register supported by Cortex R-4 to  get the interrupt source number. How I can get this number . 

Please  help me on this and also let me know if i have posted this question in wrong category. 

Thanks!
