Retrigger PSCOUTr1 On External Event
Figure 14-9.
Note:
Figure 14-10. PSCOUTr0 retriggered by PSCr Input A (Level Acting)
Note:
PSCOUTr1 output can be reset before end of On-Time 1 on the change on PSCr Input B. The polarity of
PSCr Input B is configurable thanks to a sense control block. PSCr Input B can be configured to do not act
or to act on level or edge modes. PSCr Input B can be the Output of the analog comparator or the PSCINr
input.
As the period of the cycle decreases, the instantaneous frequency of the two outputs increases.
