21.3.3.2.2 One-shot Mode
2010-09-06 - d0001_Rev1.00
Figure 21.2. LETIMER State Machine for Free-running Mode
Note that the CLEAR command bit in LETIMERn_CMD always has priority over other changes to
LETIMERn_CNT. When the clear command is used, LETIMERn_CNT is set to 0 and an underflow
event will not be generated when LETIMERn_CNT wraps around to the top value or 0xFFFF. Since
no underflow event is generated, no output action is performed. LETIMERn_REP0, LETIMERn_REP1,
LETIMERn_COMP0 and LETIMERn_COMP1 are also left untouched.
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 LETIMERn_REP0 times, i.e.
the timer underflows LETIMERn_REP0 times.
Note
LETIMERn_REP0 can be written while the timer is running to allow the timer to run for longer periods
at a time without stopping. Figure 21.3 (p. 289) .
(RUNNING or START)
and ! STOP
CNT = = 0
Note that write operations to LETIMERn_REP0 have priority over the decrementation
operation. So if LETIMERn_REP0 is assigned a new value in the same cycle it was
supposed to be decremented, it is assigned the new value instead of being decremented.
