1.10 EVSYS Trigger
This example application demonstrates how to use the EVSYS peripheral library to setup autonomous, low-latency and configurable communication between peripherals.
Description
This example application shows how to use the EVSYS peripheral library to route the events generated by the switch to generate pulse through CCL peripheral without CPU intervention.
