Have a look at section 5.4.13 on page 52 of the same document.
Essentially this prevents accidental? sabotage of the VIC
by processes in User mode.
I don't know whether a user write to a VIC register is simply
ignored or if an exception occurs. That might be documented in
the Arm PrimeCell VIC documentation PL190 (link on page 44
of the UM).

Hope this helps,
Danish
