20.3.4 Example Applications
Pulse Width or Time Between Events
The following steps explain how to measure the pulse width or time between events.
1. Select the same input pin to perform a pulse-width measurement between the start and
2. Set the counter to start on the start condition and stop on the stop condition, latch on the
3. In the interrupt handler, read out the counter to determine the pulse width or time interval
Time-Stamp External Events
The following steps explain how to time-stamp external events.
1. Set the trigger for the desired event type.
2. Set the counter to run continuously, latch on the start (and/or stop) condition, and gen-
3. In the interrupt handler, read out the counter as an event timestamp.
Measure Time Interval from a Software Start to an External Event
The following steps explain how to measure the time interval between a software start and
the occurrence of an external event.
1. Set up the counter to run continuously, latch on the stop condition, and generate an
2. Set up the stop condition for the event of interest.
3. Reset the counter via ICCSR at the software start.
4. In the interrupt handler, read the counter as a time duration.
