Event Timing
Figure 5-3.
Having 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 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.
An event normally lasts for one peripheral clock cycle, but some event sources, such as low
level on an I/O pin, will generate events continuously. Details on this are described in the
