15.6.4.7 When One-shot Position Detection and Timer
Underflow
The output timing change of the operation of the One-shot Position Detection and
Reload Timer underflow is shown in Figure 15.6-23.
■ When One-shot Position Detection and Timer Underflow
Same as operation of position detection and timer underflow except that no further position detection will
be recognized after first valid position detection until it is changed to ANY OTHER operation mode. Pin
OPTx output waveform is shown as in Figure 15.6-23.
In order to use this method, the reload timer should be used in " Single Shot Mode". TIN0O must be longer
than two machine cycles.
