Figure 6-3. Event routing network.
Four multiplexers means that it is possible to route up to four 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.
6.5 Event Timing
An event normally lasts for one peripheral clock cycle, but some event sources, such as a low level on an I/O pin, will
generate events continuously. Details on this are described in the datasheet for each peripheral, but unless otherwise
stated, an event lasts for one peripheral clock cycle.
