Logic Analyzer Window

The Logic Analyzer is a time-based graph that:

• Shows a maximum of 4 variables when connected to the target. Watchpoints, also known as Access Breakpoints, reduce the number of variables that can be monitored.
• Shows global and static variables only. Automatic variables inside a function are not shown. For details refer to Restrictions.
• Expects a stable trace connection. Lost trace packets lead to incomplete data. Refer to Status Bar for information about trace errors.

To display variables using the Logic Analyzer:

1. Enable Timestamps and select a appropriate Prescaler value to define the granularity of the timestamps.
2. Add the variable you want to watch to the Logic Analyzer.

Notes

• Variables defined for the Logic Analyzer do automatically configure the trace options and invoke data read/write events for those variables. These events can be viewed in the Instruction Trace window.
