trigger occurs, set the trigger to the module entry address plus 08 hex. (This
assumes that there is no immediate data in the instruction stream.)
No activity on activity indicators
Ensure that the Threshold settings in the Format menu match the logic
family being probed.
Check for loose cables, board connections, and preprocessor interface
connections.
Check for bent or damaged pins on the preprocessor probe.
Capacitive loading
Excessive capacitive loading can degrade signals, resulting in incorrect
capture by the preprocessor interface, or system lockup in the
microprocessor. All preprocessor interfaces add additional capacitive loading,
as can custom probe fixtures you design for your application. To reduce
loading, remove as many pin protectors, extenders, and adapters as possible.
Careful layout of your target system can minimize loading problems and
result in better margins for your design. This is especially important for
systems that are running at frequencies greater than 50 MHz.
No trace list display
If there is no trace list display, it may be that your trigger specification is not
correct for the data you want to capture, or that the trace memory is only
partially filled.
Check your trigger specification to ensure that it will capture the events
of interest.
Try stopping the analyzer; if the trace list is partially filled, this should
display the contents of trace memory.
