To synchronize the inverse assembler
•
Identify a line on the display that you know is the first state of an
instruction fetch.
•
Roll this line to the top of the listing.
•
Press the Invasm Options softkey at the top of the screen.
This will cause the Invasm Options submenu to appear.
•
Press the Align softkey.
The listing will inverse assemble from the top line down. Any data before this
screen is left unchanged. Rolling the screen up will inverse assemble the
lines as they appear on the bottom of the screen. If you jump to another area
of the listing by entering a new line number or by rolling the screen down,
you may have to re-synchronize the inverse assembler by repeating the
described steps.
Each time you inverse assemble a block of memory, the analyzer will keep
the alignment information for that block. Pressing the Align key clears the
alignment information from the top of the screen to the end of the
acquisition. You can inverse assemble several different blocks in the analyzer
memory, but the activity between those blocks will not be inverse assembled.
