The Event Routing Network consists of eight software configurable multiplexers that control how
events are routed and used. This is called Event Channels and it enables up to eight parallel
event configurations and routings. The maximum routing latency between two peripherals is two
Peripheral clock cycles. The Event System works in both Active mode and Idle sleep mode.
