Figure 12-37. PSC behavior versus PSCn Input A in Mode 14
The output frequency is not modified by the occurrence of significative edge of retriggering input.
Figure 12-38. PSC behavior versus PSCn Input B in Mode 14
The output is deactivated while retriggering input is active.
The output of the PSC is set to an inactive state and the corresponding ramp is not aborted. The output
stays in an inactive state while the Retrigger/Fault input is active. The PSC runs at constant frequency.
