Exception Trace Window

The Exception Trace window displays statistical data for the Trace exception records captured in the Trace buffer.

Exception Trace Records Window

The Trace Exception window displays the following information for each exception:

Exception DataDescription
NumException Number (0..15 – Core Exceptions, 16.. – External Interrupts).
NameException Name.
CountNumber of times an exception happened.
Total TimeTotal Time spent in this exception.
Min & Max Time InMinimum and maximum time spent in this exception.
Min & Max Time OutMinimum and maximum time spent out of this exception.
First TimeThe time when this exeception was first entered.
Last TimeThe time when this exeception was last entered.

Note

  • The Count, Total Time and Min & Max Time In values don't include the time taken by higher priority exception interrupts that may have occurred while servicing an interrupt.  The time to process the higher priority interrupt is accounted for in the statistics for that higher priority interrupt.
  • Data in the window can be sorted (from highest values to lowest) by clicking on the desired table column header.
  • Double-clicking inside the Exception Trace window clears all the statistics.
