Figure 16-33. PSC behaviour versus PSCn Input A in Mode 9
The output frequency is not modified by the occurence of significative edge of retriggering input.
Only the output is disactivated when significative edge on retriggering input occurs.
Note: In this mode the output of the PSC becomes active during the next ramp even if the Retrig-
ger/Fault input is actve. Only the significative edge of Retrigger/Fault input is taken into account.

The retrigger event is taken into account only if it occurs during the corresponding On-Time.
