Illegal Operation fault
Interruptions:
Privileged Operation fault
Register NaT Consumption fault
Reads of control registers reflect the results of all prior instruction groups and

uses a modified resource.
Control register writes are not implicitly synchronized with a corresponding control
register read and requires data serialization.
