[ARMv7] Exception Priorities?

Hi,

I see registers PRIn (starting from E000E400) are registers for changing priorities of external interrupts.  But, after searched over my manuals, I have not found what are registers for changing priorities for system exceptions (no.1 -- no.15).    Could someone tell me?

Thanks in advance.

    Sorry, I mean No.4 - No.15 since No.1 to No.3 have fixed priorities.
