An application contains a delay loop. How long is the delay?
For this problem, a Time Between Events trigger is very useful. Suppose the delay
routine is called Delay. For debugging purposes, a label EndDelay has been added
at the address of the delay routine’s return statement. Set the Start Timer tab to a
program memory fetch of address Delay, and the Stop Timer tab to a program
memory fetch of address EndDelay. Check the Ignore FNOP Cycles box, and leave
both halt check boxes unchecked. Apply the trigger, open the trace memory window,
then run. After EndDelay is reached, the trace memory window will fill and the largest
time stamp value will be the time between the two events.
