21.3.3.4 One-shot Mode
The one-shot repeat mode is the most basic repeat mode. In this mode, the repeat register LETIMERn_REP0 is decremented every
time the timer underflows, and the timer stops when LETIMERn_REP0 goes from 1 to 0. In this mode, the timer counts down LETI-
MERn_REP0 times, i.e. the timer underflows LETIMERn_REP0 times.
Note:
Note that write operations to LETIMERn_REP0 have priority over the timer decrement event. If LETIMERn_REP0 is assigned a new
value in the same cycle as a timer decrement event occurs, the timer decrement will not occur and the new value is assigned.
LETIMERn_REP0 can be written while the timer is running to allow the timer to run for longer periods at a time without stopping.
