Retrigger PSCOUTn1 On External Event
Figure 12-16. PSCOUTn0 retrograde by PSCn Input A (Edge Retriggering)
Note:
Figure 12-17. PSCOUTn0 retriggered by PSCn Input A (Level Acting)
Note:
PSCOUTn1 output can be reset before end of On-Time 1 on the change on PSCn Input B. The polarity of
PSCn Input B is configurable thanks to a sense control block. PSCn Input B can be configured to do not
act or to act on level or edge modes. PSCn Input B can be the Output of the analog comparator or the
PSCINn input.
As the period of the cycle decreases, the instantaneous frequency of the two outputs increases.
