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!
Yes, PL192 also has a hardware stack for the priority level.
