17.3.1 Output target selection register n (ELSELRn) (n=00~14)
The ELSELRn register links each event signal to the event receiver peripheral function (link target
peripheral function) to run when the event accepts the event. You cannot link multiple event inputs to
the same event output destination (event acceptor). Otherwise, the event receiver's peripheral
functionality may operate uncertainly and the event signal may not be accepted properly. Also, you
cannot set the event link occurrence source and event output destination to the same function.
The ELSELRn register must be set during the period when the peripheral functions of all event
outputs do not generate an event signal.
The correspondence between the ELSELRn register (n=00~14) and the peripheral functions is
shown in Table 17-2. The corresponding operation between the config value of the ELSELRn register
(n=00 ~14) and the link target peripheral function when receiving the event is shown Table 17-3.
