14.3 Registers Controlling ELC
Table 14-1 lists the registers controlling ELC.
Control register
14.3.1 Event output destination select register n (ELSELRn) (n = 00 to 09)
An ELSELRn register links each event signal to an operation of an event-receiving peripheral function (link destination
peripheral function) after reception.
Do not set multiple event inputs to the same event output destination (event receive side). The operation of the event-
receiving peripheral function will become undefined, and event signals may not be received correctly. In addition, do not
set the event link generation source and the event link output destination to the same function.
Set an ELSELRn register during a period when no event output peripheral functions are generating event signals.
Table 14-2 lists the correspondence between ELSELRn (n = 00 to 09) registers and peripheral functions, and Table 14-
3 lists the correspondence between values set to ELSELRn (n = 00 to 09) registers and operation of link destination
peripheral functions at reception.
