Figure 6-3.
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 devices contain all peripherals. This only means that a peripheral is not available
for generating or using events. The network configuration itself is compatible between all
devices.
