Is the SYST_CVR (0xE000E018) register accessible in USER mode ?

Hi, 

I'm using M33 core. when I switch to User mode and try to access system timer register  SYST_CVR to read the current value I got an exception raised.

So my question is, is that register accessible in user mode ? if not, what are the steps to read it when I'm on user mode ? 

Thanks,
