The EVSYS can output three event channels asynchronously on pins. The output
signals are called EVOUT[2:0].
- 1.Configure which event channel (one of
SYNCCH[1:0] or ASYNCCH[3:0]) is output on which EVOUTn bit by writing to
EVSYS.ASYNCUSER10, EVSYS.ASYNCUSER9, or EVSYS.ASYNCUSER8, respectively.
- 2.Optional: configure the pin
properties using the port peripheral.
- 3.Enable the pin output by writing '1' to the respective EVOUTn bit in the Control A
register of the PORTMUX peripheral (PORTMUX.CTRLA).
