Figure 16-31. PSC behaviour versus PSCn Input A in Mode 8
The output frequency is modulated by the occurence of significative edge of retriggering input.
Figure 16-32. PSC behaviour versus PSCn Input B in Mode 8
The output frequency is modulated by the occurrence of significative edge of retriggering input.
The retrigger event is taken into account only if it occurs during the corresponding On-Time.
Note: In one ramp mode, the retrigger event on input A resets the whole ramp. So the PSC
doesn’t jump to the opposite dead-time.
