21.5 Operations
21.5.4.7 When One-shot Position Detection and Reload
Timer Underflow
The output timing change of the operation of the one-shot position detection
and reload timer underflow is shown in Figure 21.5-23.
■ When One-shot Position Detection and Reload Timer Underflow
The operation of one-shot position detection and reload timer underflow is the same as that of
the position detection and reload timer underflow, except that after the first valid position is
detected, no further position detection is recognized until the operation mode is changed from
one-shot position detection and reload timer underflow to another operation mode. The OPTx
output waveform is shown in Figure 21.5-23.
In order to use this method, use the 16-bit reload timer in one-shot mode. TIN0O must be
longer than two machine cycles.
