Retrigger PSCOUTn1 On External Event
Figure 16-15. PSCOUTn0 retriggered by PSCn Input A (Edge Retriggering)
Note:
Figure 16-16. PSCOUTn0 retriggered by PSCn Input A (Level Acting)
Note:
PSCOUTn1 ouput can be resetted 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.
