A.3.5 Filter data memory
How do I filter on data memory?
See Filter Trace Example - Data Memory.
A.4 Additional Debugging Examples
A.4.1 Time between interrupts
An application contains an interrupt. How long is the time between interrupts?
There are two ways to measure this: using a filtered trace or using time
between events.
Solution A: Filter Trace
Using the Filter Trace, capture every time the interrupt service routine (ISR)
starts. The difference between the Trace Memory Window time stamp of one
start address and the next will be the length of the ISR.
To clear all break, trace and trigger points, select Debug>Clear All Points.
Select Debug>Complex Trigger Settings to open the Complex Trigger
Settings dialog.

Set up the Complex Trigger Settings dialog for Filter Trace on Program
Memory. Ignore FNOP Cycles should not be checked.
