Section 3 Memory Management Unit (MMU)
When single virtual memory is supported (MMUCR.SV = 1) and privileged mode is engaged
(SR.MD = 1), all process resources can be accessed. This means that ASIDs are not compared
when single virtual memory is supported and privileged mode is engaged. The objects of address
comparison are shown in figure 3.7.
