Event Routing Network
Software-generated events last for one clock cycle and will overwrite events from other event
generators on that event channel during that clock cycle.

they are decoded.
Table 6-1.
The event routing network routes the events between peripherals. It consists of eight multiplex-
ers (CHnMUX), which can each be configured to route any event source to any event users. The
output from a multiplexer is referred to as an event channel. For each peripheral, it is selectable
if and how incoming events should trigger event actions. Details on cinfigurations can be found
in the datasheet for each peripheral. The event routing network is shown in
73.
