To Align The Inverse Assembler - HP 16600A Series User Manual

To align the inverse assembler

The CPU32 microcontroller does not indicate externally which word
fetched is the beginning of a new instruction. You may have to "point"
to the first state of an instruction fetch to align the inverse assembler.
Once aligned, the inverse assembler will disassemble from this state
through the end of the screen.
Use the following procedure to align the inverse assembler:
1 Select a line on the display that you know contains the first word
of an instruction fetch.
2 Roll this line to the top of the display.
Do not roll the instruction to the line number field at the left center
screen. In the Listing Menu figure on page 99, line 1 is the top of the
display.
3 Select the appropriate field for your analyzer.
a For the HP 16600/700 series analyzers, select "Invasm," then
select "Align."
b For the other logic analyzers, select "Invasm Options" and use
the "Code Synchronization" submenu.
4 Select "Align."
The listing inverse assembles from the top line down. Any data before
the top of the display is left unchanged.
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
