Figure 9-1. Event system overview and connected peripherals.
The event routing network consists of eight software-configurable multiplexers that control how events are routed and
used. These are called event channels, and allow for up to eight parallel event routing configurations. The maximum
routing latency is two peripheral clock cycles. The event system works in both active mode and idle sleep mode.
