An external event can be programmed to be detected on one of the clock sources (XC0, XC1,
XC2) or TIOB. The external event selected can then be used as a trigger.
The parameter EEVT parameter in TC_CMR selects the external trigger. The EEVTEDG param-
eter defines the trigger edge for each of the possible external triggers (rising, falling or both). If
EEVTEDG is cleared (none), no external event is defined.
If TIOB is defined as an external event signal (EEVT = 0), TIOB is no longer used as an output
and the TC channel can only generate a waveform on TIOA.
