Processor-Specific Output Format
The logic analyzer captures all bus cycles. This includes background and
coprocessor cycles as well as code cycles.
A "c" marks coprocessor activity, and background activity is marked with a
"b". The "c" and "b" are displayed in the first column of the mnemonic/hex
field. Acquisitions of coprocessor and background cycles may be individually
enabled/disabled via the trigger menu.
General Missing Terms
Depending on the configuration of the microcontroller, the inverse assembler
may be unable to supply all the of the information it can supply. For example,
if ~DS (data strobe) is not valid, internal cycles cannot be captured.
Filtering
The CPU32 inverse assembler is capable of suppressing certain acquired
cycles from the display, thus allowing the user to focus on and display more
cycles of interest. The filter softkeys are part of the "Invasm Options"
submenu. "Invasm Options" must be pressed to display the submenu.
Cycle suppression is broken down into the following categories: extension
words, unexecuted prefetches, branches, calls and returns, other
instructions, data reads, and data writes.
Extension words and unexecuted fetches are suppressed without regard to
user mode or supervisor mode because they do not affect the display of
executed mnemonics.
All other categories may suppress based on the user mode, supervisor mode,
or both. These categories suppress actual executed mnemonics for the
display.
