15.2.3.2 I/O Lines
The EVSYS can output three event channels asynchronously on pins. The output
signals are called EVOUT[2:0].
- 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.
- Optional: Configure the pin properties using the port peripheral.
- Enable the pin output by writing
‘
1
’ to the respective EVOUTn bit in the Control A (PORTMUX.CTRLA) register of the PORTMUX peripheral.
