15.3.2.1 Event User Multiplexer Setup

The event user multiplexer selects the channel for an event user. Each event user has one dedicated event user multiplexer. Each multiplexer is connected to the supported event channel outputs and can be configured to select one of these channels.

Event users which support asynchronous events also support synchronous events. There are also event users that support only synchronous events.

The event user multiplexers are configured by writing to the corresponding registers:
  • Event users supporting both synchronous and asynchronous events are configured by writing to the respective asynchronous User Channel Input Selection n register (EVSYS.ASYNCUSERn).
  • The users of synchronous-only events are configured by writing to the respective Synchronous User Channel Input Selection n register (EVSYS.SYNCUSERn).

The default setup of all user multiplexers is OFF.
