13.18.6.2.3 User Multiplexer Setup
The user multiplexer defines the channel to be connected to which event user. Each user multiplexer is dedicated to one event user. A user multiplexer receives all event channels output and must be configured to select one of these channels, as shown in Figure 13-80. The channel is selected with the Channel bit group in the User register (USERm.CHANNEL).
The user multiplexer must always be configured before the channel. A list of all user multiplexers is found in the User (USERm) register description.
