The sharing information (SH) determines whether the PTEH.ASID and the ASID in the TLB entry
are compared. ASIDs are compared when there is no sharing between processes (SH = 0) but not
when there is sharing (SH = 1).
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 3.8.
