High-resolution timer (HRTIM) RM0440

Figure 215. Short distance set/reset management for narrow pulse generation
If the set and reset events are generated within the same
t
HRTIM
period, the reset event has
the highest priority and the set event is ignored.
If the set and reset events are generated with an interval below
t
HRTIM
period, across 2
periods, a pulse of 1
t
HRTIM
period is generated.
If the set and reset events are generated with an interval below 2
t
HRTIM
periods, a pulse of 2
t
HRTIM
periods is generated.
If the set and reset events are generated with an interval between 2 and 3
t
HRTIM
periods,
the high-resolution is available if the interval is over 2 complete
t
HRTIM
periods.
