Figure 6-3.
Having eight multiplexers means that it is possible to route up to eight events at the same time.
It is also possible to route one event through several multiplexers.
Not all XMEGA parts contain all peripherals. This only means that peripheral is not available for
generating or using events. The network configuration itself is compatible between all devices.
