To use the inverse assembly options
The Inverse Assembly Options menu contains two functions: display filtering
with Show/Suppress selections, and Code Synchronization. To access the
Inverse Assembly Options menu, press the Invasm Options softkey at the top
of the screen.
Show/Suppress
The Show/Suppress settings determine whether certain classes of acquisition
states are shown or suppressed on the logic analyzer display. The settings
for the various operations do not affect the data which is stored by the logic
analyzer, they only affect whether the acquired data is displayed or not. The
same data can be examined with different settings, for different analysis
requirements.
This function allows faster analysis in two ways. First, unneeded information
can be filtered out of the display. Second, particular operations can be
isolated by suppressing all other operations. For example, I/O branches can
be shown, with all other operations suppressed, allowing quick analysis of I/O
branch flow.
N o t e :
If the X or O pattern markers are turned on, and the designated pattern is
found in a state that has been Suppressed with display filtering, the
following message will appear on the logic analyzer display: "X (or O)
pattern found, but state is suppressed."
Code Synchronization
The Code Synchronization enables the inverse assembler to resynchronize
with the microcontroller code (see next section).
