Seeing Details of the MMU Translations
Table details for a selected logical address
The lowest level of detail you might like to see is the content of one of the tables
used to map a particular logical address. You might choose Display→MMU
Translations... and in the dialog box, click on MMU Tables, enter Address 40f8h,
and click on Table Level to obtain C; or enter a command like: display
mmu_translations tables 40F8h level C. The emulator would show the details of
Table C where it is used to map logical address 40F8. There might be a great many
Table C's, but this command will only show the Table C that is used to map the
logical address you specified in your command.
In the example display of table details:
•
•
•
382
The LOCATION column shows the physical address of each indexed location
in Table C.
The TBL/PAGE column shows the base addresses of physical pages indicated
by each location in Table C.
The first indexed location in Table C shows that its associated physical page
has been accessed, but not modified ("U" bit = "y", and "M" bit = "n").
