Displaying Captured Data

	You can use the Serial Analysis toolset to convert streams of serial data
	into parallel words which are easier to view and analyze.
	You can use the System Performance Analysis toolset to do things like:
	isolate the root cause of performance bottlenecks, measure function
	execution times, view the occurrence rate of an event, analyze bus
	occupation and bandwidth, analyze bus stability, analyze jitter or time
	dispersion, etc.

Intermittent Data Errors

Unwanted Triggers

If the captured data doesn't look correct

Check for poor connections, incorrect signal levels on the hardware, incorrect logic levels under the logic analyzer's Config tab, or marginal timing for signals.

If you are using an inverse assembler or a pipeline, triggers can be caused by instructions that were fetched but not executed. To fix, add the prefetch queue or pipeline depth to the trigger address.

The depth of the prefetch queue depends on the processor that you are analyzing, and can be quite deep.

Another solution which is sometimes preferred with very deep prefetch queues is to add writes to dummy variables to your software. Put the instruction just before the area you want to trigger on, then trigger on
